Actually, the primary factor in a baby’s ability to float is the ability to take air into the lungs. To maintain this access to air, the child must adjust his/her posture. The difference in positioning for an adult can be inches. For a baby, this adjustment is reduced to centimeters. If a child’s body posture is just a few centimeters off, it can make the difference between the face being submerged or the child having access to air.

The reason for this is multifaceted. First, repetition and consistency are crucial elements of learning for young children. Research shows that short, more frequent lessons result in higher retention. Second, most children have fairly short attention spans and will not be able to focus on the task for longer and we want to take advantage of the best time for learning. A third reason is that, though the pool temperature is maintained at 78-88 degrees, the temperature is still lower than your child's body temperature. Lessons are work and therefore will also be losing body heat. Instructors check students regularly for temperature fatigue since this is an indicator of physical fatigue.

Every child is unique. However, many parents report that once their young children have mastered learning to swim, the resulting confidence in their abilities engenders a positive self-concept that is often demonstrated in other aspects of their personalities. There are also obvious health and other psychological gains.

Children often fuss during the first few lessons because they are in a new environment and around new people. As your child becomes more confident in his/her ability in the water, the fussing will decrease. It is not unlike the first time you tried a new exercise class or were asked to perform a task at work that you’d never done before: the first time you try a new task it is always challenging, until you get the hang of it. It is the same for your young child. Your child is learning to perform a skill that he/she’s never done before.
