The most common question a parent could ever ask a swim teacher is, when will my child learn to swim? It’s a harmless and rightfully direct inquiry. Yet believe it or not, seasoned instructors know this is one of the most complex and controversial questions we could ever try to answer about your child.
Why is that? A better understanding of the complexity behind attempting to gauge when someone can safely start swimming can be explained by by discussing certain aspects – four to be exact. This entry is part of a four-part entry on the precursors of learning how to swim. Today I will discuss the first aspect: The Buoyancy Aspect.
Part 1: The Buoyancy Aspect. Talking about buoyancy is talking about a body’s ability to be forced upwards to float – as known as hydrodynamics. Human bodies typically experience a 50-80% total body weight loss when submerged in the pool. This means the water has the power to hold us up but not 100% (otherwise we’d be walking on water, right?). The trouble is everyone’s specific gravity – which is the ratio of the weight of your body to the weight of the water it displaces – is different and for the most part, totally uncontrollable. Meaning it’s not up to your child if they are a sinker or a floater. Some issues do help and some hinder. For example, adipose tissue (also known as body fat) has a specific gravity that promotes floating, whereas muscle mass or heavier bone structures have a specific gravity that promotes sinking. Also, our center of mass or the “down force” located near the hips sometimes outweighs your center of gravity or the “up force” located in the chest. Meaning many can only stay horizontal for a few seconds before legs start to sink and fully submerged a body in a vertical position. What’s the point of all this physics gibberish? If your fearful swimmer cannot feel they float well enough, they are going to feel panic instead. Panic causes contraction of the muscles, which further complicates (or weighs down) the issue. Let me throw in just one additional point about the buoyancy aspect: Water properties are 830-times thicker than air with 12-times the resistance coming at you from every angle. If you have limited strength or floating powers, swimming can feel like trying to survive in quicksand. Imagine how be intimidating that can be to a small child!
Next entry: Part 2, or The Memory Aspect!
The knowledge swim season is just around the corner can cause many families to have an initial reaction that resembles more of a cringe than one of celebration. This is because not all children fall in love with the water upon first splash. Even if you were a champion fish yourself, your child’s trepidation over swimming is often immune to your liquid-loving DNA or best parenting efforts. In fact, how a water fear develops, whether it is one imagined or actually experienced by the child, can be quite uncontrollable. Water fears develop either from something imagined or an actual negatively experienced swim experience. So something as simple as seeing an older sibling take a swim lesson – or as serious as their falling into a pool – can create a water fear.
I once had a dissatisfied parent explain to me I wasn’t teaching enough to their already-advanced 1-1/2 year old child. I explained I was doing everything I was able to do for a child of this age, but that cognitive and physical ability limit swim skills.

The longer I teach, the more conscious I become about enforcing water safety skills and pool rules. Well, I also think getting older and pregnant makes me realize all the dangers that exist for kids out there. You just have to pick up your local paper and read about the latest drunk driving teen crash to get an idea it does happen in your backyard.
