Athletic Talent: Every Child’s Birthright

By Charles Solis | May 29, 2018 | Comments Off on Athletic Talent: Every Child’s Birthright

OK, so I’ll come right out and say it. We believe that every child, providing they have an intact brain, has the potential to become an athlete. Indeed, based on the science and our experience, we are absolutely convinced that every child can become an athlete. Let’s take a look at elite athletic performance a little closer so I can show you what I mean and why.

2018 is turning out to be quite a year for watching extraordinary athletic skill on display. It started off with my beloved Philadelphia Eagles stunning fans of American football with their wonderful display of athleticism and grit as they surprised everyone and won the Super Bowl. Then there was the Winter Olympic Games in South Korea earlier this year. Then, Philadelphia’s Villanova Wildcats basketball team steamrolled every opponent they faced to win the NCAA championship. And this summer, the best football (soccer) players in the world will test their skills at the FIFA World Cup in Russia.

When we watch athletes perform at such a high level we marvel at their technical skill, balance, coordination, stamina, and strength. Even those athletes who fail to medal or make the starting team are inspirational to watch because all of them are operating at a level of physical ability that most of us can only dream of reaching. Or are they? Is their talent for skiing, snowboarding, ice skating, running, kicking, throwing, something that is available only to a small number of gifted people? Or are all of us potentially capable of performing at high levels of physical excellence? If so, what does it take to get to the highest levels?

To answer those questions we need to look beneath the surface of the athletic performance because there is far more going on than meets the eye. What most people don’t realize is that for every one of these athletes, behind the scenes, there is a highly developed and finely tuned brain directing those bodies. We have such a tendency to think of the brain only in terms of its cognitive or intellectual prowess. This became very clear to me a few years ago when my brother suffered a stroke that left him with significant motor problems while his cognitive abilities remained intact. Despite the loss of motor function, which is only possible because of the brain, many people said to me that it was a relief to know that his brain wasn’t damaged! What?!!

Of course, there are good reasons for our focus on cognitive function.  In comparison with other mammals, our abilities to create, reflect, analyze, and communicate are unmatched. We can’t say the same thing about physical ability. The elephant is stronger than the strongest human. The cheetah, at 70 mph, can easily outsprint even the fastest of Olympic sprinters. Gold medal winner, Usain Bolt was clocked at just under 28 mph in his fastest race so the cheetah easily doubles his speed. The point is that when it comes to specific physical skills like speed and strength we’re really not so special. So it is easy to take human mobility for granted.

What is beautiful about sports and athletic endeavors, in general, is that they spotlight the combination of human mobility with human cognition and the incredible level of brain development necessary to make those sports possible.

My father was a gymnast so I’ve long been a fan of Olympic gymnastics. Many years ago I taught gymnastics to very young children. The combination of coordination, balance, kinesthetic awareness, strength, speed, agility, and flexibility needed to perform gymnastic routines is mind-boggling. However, what I really appreciate about the sport is how it combines all of those physical attributes with extraordinary creativity. For a stellar example of this, check out this gold medal performance by Epke Zonderland (Netherlands) on the high bar in the 2012 London Summer Olympics. It was so spectacular that it left the crowd gasping in awe and compelled his two closest competitors to embrace him in admiration.

“Practice doesn’t make perfect.

Practice makes myelin, and myelin makes perfect.”

Daniel Coyle, The Talent Code

This is brain development and organization at its highest level. What all elite athletes have in common is that they are devoted to developing their brains. Most likely, very few of them are even aware that this is what they are doing. But that is the bottom line. It all boils down to the basics of good brain development.

If you’ve been following this blog this will sound quite familiar. If not, check out my post on Harnessing Brain Plasticity. The use of function with increased frequency, intensity and duration results in increased dendrite growth, increased neural connections and increased production of myelin. Translation? Practice, practice, practice. Try, fail, make corrections, and try again. This is neuroplasticity in action. It creates the neural pathways required for learning new skills and cements those skills into memory. This is how you grow the human brain!

So where does that leave your kids and the rest of us who are not elite athletes? Well, surprisingly, provided that our brains are functioning well it leaves us in pretty good shape. The truth is that each of us is capable of being his or her own Olympian. Our objective is to give children the opportunity to develop to their full potential whatever that might be. We do that by ensuring that their brains are well developed and functioning well. Two things are required. First, we must develop the function of mobility along the ancient progression (tummy crawl, creep, then walk) that is most advantageous for both good brain development/organization and good physical function. Second, we must use the function of mobility with sufficient frequency, intensity and duration. Do that and your kids will be in good shape. They’ll have the coordination, balance, stamina, and strength to enjoy any athletic endeavor they choose. They’ll have athletic talent.

I’ve said this before but it bears repeating. Does this mean that every child will grow up to be a superstar? Not at all. But becoming a superstar in any endeavor, especially in childhood, isn’t the objective. At least it shouldn’t be the objective. It’s certainly not our objective. Our contention is that every child is born with the birthright to be an athlete, not an Olympian. There is a big difference between having talent and having superstar talent. How far a child takes their physical talent will depend on things like their passion for a particular sport, their individual motivation (not your motivation!), their level of discipline, the kind of coaching they receive, etc. Our job and your job is to give them the springboard from which to launch. If we do that well they’ll have tons of physical options to choose from and we’re perfectly happy to let the kids decide where their athletic talent leads them!

The Best Mat for Tummy Time – Tumbl Trak Mat

By Charles Solis | May 22, 2018 | Comments Off on The Best Mat for Tummy Time – Tumbl Trak Mat

Coach John Wooden, former head basketball coach at UCLA, won ten NCAA national championships in a 12-year period, including a record seven in a row.

Coach was fond of saying that it’s the little details that are vital to creating success on the court and in life.

His wisdom also applies to the development of young children. I’ve got a little details tip for you today that can make all the difference in getting your little one’s mobility off and running… or should I say crawling?

Assuming that the brain is functioning well, every newborn baby is an athlete in the making. The mobility pathway that eventually leads to elite physical performance begins at birth and what happens in the first year of life is critically important.

In the early months of life the main mobility objective is to develop good head and trunk control and for your baby to become comfortable with being in the prone position (on the tummy). But the grand prize is crawling on the tummy for transportation. And this is where paying attention to little details can make a huge difference.

Crawling on the tummy is difficult work! Your baby has to move across the floor with the entire torso in full contact with the surface. Naturally, this causes a lot of friction, thus making movement more difficult. To the extent we can reduce friction, we can make crawling easier. Try crawling on a plush carpet compared to a linoleum floor and you will see what I mean. So, what to do?


Little Details

“It’s the little details that are vital. Little things make big things happen.” Coach John Wooden, UCLA Bruins

The answer lies in the little things. In order to facilitate movement we need to minimize friction with a surface that is smooth (like linoleum) and firm, but not hard. We’ve done the research and tried all kinds of surfaces in our work with children who have mobility problems. The best product we have found for them and for little babies is the Tumbl Trak Tumbling Mat. It is smooth, firm (but not hard), colorful, measures 4 ft x 8 ft and folds neatly for storage. The mat comes in two thicknesses, 1-3/8 inch or 2 inches.

For little babies, the thinner mat is perfectly adequate. If you’d like to use the mat for tumbling when your child is older, then the 2 inch mat is the way to go.

Many parents place their babies on cloth baby gyms or soft foam ABC play mats or tiles. These may be cute and comfortable but they are entirely unnecessary and make movement more difficult, not easier.

Cloth baby gyms usually have a mobile overhead so parents tend to place their baby on the back so baby can see the mobile. That’s nice for vision but it interferes with mobility because babies move on the tummy not the back. You can however place your baby on the tummy when using the cloth baby gym. And when your baby needs a break from tummy time you can flip her over and she can enjoy the mobile. You can also use it in conjunction with the Tumbl Trak Mat to provide an incentive to move forward.

Foam ABC play mats or tiles make for a cute room decoration and they cushion falls nicely but they also make movement difficult because they have a rough non-skid texture which creates friction. We want to reduce friction, not increase it.

You have to be careful how you use this kind of equipment. Our advice is don’t waste your money on things your baby doesn’t need especially if they interfere with good brain development.

The Tumbl Trak Tumbling Mat is not cheap. So, think of it as an investment in your child’s future. Nothing influences human brain development and organization more than mobility. How that mobility happens in the first year of life is critical to everything that follows. Your investment will pay huge dividends for years to come.

If you decide to purchase this mat we recommend placing it outdoors for several days to a week so that the vinyl covering can outgas. Once you’ve done that you are good to go. Let us know how it works for you and feel free to write with questions.


Kickstarting Mobility

By Charles Solis | May 15, 2018 | Comments Off on Kickstarting Mobility

We are often asked, “What is the most important thing that I can do for my child’s brain?”  The answer may surprise you. Put your child in the prone position, which is to say, on his tummy! That’s it. No fancy, expensive toys or equipment. No mommy/baby classes. No iPads. All you need is a comfortable surface and the time to be with your baby. This one practice will do more for your child’s brain than anything else you can do. Put him on his tummy! Pretty simple, right?

So, let’s dive right in and talk about tummy time. Parents are sometimes aware that giving their child tummy time is a good idea but they are almost never told how to do it or why it’s important. It is one of the reasons that most parents avoid it like the plague. And, unfortunately, many children are paying a price for that.

Tummy time is one of the most important developmental opportunities you can give your baby but it has to be done right. We’ll start with why it’s important and then talk about how to do it.

Why do Tummy Time

Did you know that when you place your baby on her tummy (prone position) you are not only developing her muscles but you are also developing your baby’s brain? The development of the function of mobility begins with time spent in the prone position, tummy time.

We define mobility as follows – the function we use to transport ourselves from point A to point B. The key word in that definition is transport. Mobility is useless as a function, it serves no purpose, unless it is directed towards something. That something is transportation. Developing good mobility is not complicated, but it is extremely important. Why?

All forms of mobility, including tummy crawling:

  • Facilitate brain organization
  • Increase production of myelin
  • Increase production of BDNF (brain-derived neurotrophic factor) – a protein produced in the brain during physical activity. Neuroscientists call it “Miracle-Gro for the brain” because of the proliferation of new neurons and dendrites produced whenever it is found in high concentrations.
  • Develop the senses of vision, hearing and tactile ability
  • Increase muscle strength
  • Improve coordination and balance
  • Improve posture
  • Develop breathing

Mobility is key to brain organization because the brain works as a holistic system. Everything affects everything else. Primitive brain structures are connected to higher level brain structures. As in any system, it is important that each component of the system functions well for the entire system to function well.

This concept is important to mobility’s role in brain organization because the only time that human beings use all functions simultaneously is when we are moving. Every time we use an ability, we are using and developing our brain. When we move, we use vision to see where we are going. We use hearing and receive information about our position in space by way of the inner ear. We feel our arms and legs moving through our tactile sense. We use our hands when we crawl and creep. So mobility is, in a very real sense, the glue that holds all other functions together.

There are many ways a baby can learn to move but not all of them foster good brain development and brain organization. Keep in mind that we human beings are designed to start moving for transportation on our tummies and not on our backs or our bottoms! The natural progression that all babies should experience is to begin by crawling on their tummies, then to progress to creeping on their hands and knees, then to stand and cruise (often holding onto furniture), and finally, the grand prizes of walking and running.

So, what are the best practices to make tummy time enjoyable and successful for your baby and you? We’re so glad you asked!


How to do Tummy Time


When to start?

Provided your baby is healthy, begin right from birth. Why? Because when done correctly, babies who are placed on their tummies right from birth learn to enjoy tummy time. You want your baby to enjoy tummy time. Your baby should enjoy tummy time.

In the below video of my granddaughter, she is already having a tummy time session at 3 days of age . You’ll see that even at only a few days of age she is already comfortable on her tummy.

If you have not started tummy time from birth, no worries. The beautiful thing about the human brain is that we can always make up for missed opportunity. The first step is to recognize the importance of the opportunity. Begin now and follow the steps below.


Be present

Always be with your baby when doing tummy time! When placing your baby on her tummy, always be with her so you can see her face, she can see yours, and you can pick her up as soon as necessary. If you have your baby on a mat on the floor, lay down on the floor next to her. Doing this will reassure your baby that you are always there for her no matter where she is or what position she is in. That will make her happy. And if she’s happy, you’ll be happy.



For now, aside from being clean and comfortable, the type of surface on which you place your baby is not very important. What is important is that you want to make sure there is nothing around the baby (sheets, blankets, clothing, etc.) that she can pull onto her face, thus potentially affecting her ability to breathe. So, a comfortable mattress covered with a clean sheet works just fine.



When it comes to tummy time and learning to move, remember that less is more. You want your baby to be dressed appropriately for the ambient temperature in the room. So, if the temperature is warm perhaps barefoot with just a t-shirt and a diaper will work just fine. If the temperature is on the cooler side perhaps you will want to dress your baby in a onesie or pajamas with her feet covered. Do what you think is right for the temperature. The one thing you do want to pay attention to is that the clothing should not in any way interfere with your baby’s ability to move her arms and/or legs. Provided she can move freely, you and she are in good shape.

The below video is of my grandson doing tummy time at one week of age. It’s a good illustration of all of the previous points – always being present, a comfortable surface, and appropriate dress. And, there’s a great little bonus towards the end.



In our last blog post about the second law of brain development, we talked about the importance of using the correct frequency, intensity, and duration for whatever activity we are doing with a child. For a child with an immature brain (either because of chronological age, brain-injury, or lack of development), the frequency of any activity should always be high. Whatever it is, you want to do it often.

So, you want to use high frequency. You should place your baby on her tummy at every opportunity – many times throughout the day whenever she is awake. Logical exceptions to this are when nursing or bottle feeding, changing her diaper, or just spending time snuggling. A good way to get in the habit is to roll your little one over onto her tummy after every diaper change.



Going back to our post on the second law of brain development, when dealing with a child with an immature brain (either because of chronological age, brain-injury, or lack of development), the duration of any activity should always be kept short.

So, you want to use short duration. Your baby may fuss a bit at first and that’s alright. Pick her up as soon as she begins to cry or complain too much. Talk to her, kiss her, and as soon as she is happy again place her back on her tummy. The sessions might begin with just a few seconds, but if you do it frequently enough your baby will be comfortable on her tummy. Stay attuned to your baby and if she is getting tired and fussy, stop. Eventually, you will know the right duration. As your baby gets more and more comfortable, develops good head control and gets stronger, the duration should increase.  



Since we are all born with a genetic imperative to move, most babies need very little motivation. But motivation never hurts. In the beginning use brightly colored toys, bright contrasting pictures, toys that play music and/or have bright lights. Place them just out of your baby’s reach. Move them slowly from one side to the other.


Use language

This is a good time to talk and sing to your baby. Have a conversation with her. Tell her how much you love her, how proud you are of her efforts. She wants to hear your voice! All children love music. Tummy time is a good time for you to sing to her. This will have the additional benefit of getting you in the habit of talking to your child and talking to her is the first step to developing understanding.

One more video of my granddaughter, this time at just shy of 6 months of age and already beginning to crawl for transportation. This clip shows nicely how by paying attention to all of the points in this post a child can be well on the road to independent mobility within a few months.

As you can see, creating good mobility really requires only three things:

  • placing your child in the correct (i.e. functional) position
  • providing an environment that makes movement safe and easy
  • giving your child ample opportunity to move

It’s that simple!
