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.

A baby does not need to perceive danger or be afraid to respond appropriately to being underwater. If a baby has learned to roll over and float when he needs air, he doesn't need to perceive danger in order to respond in this manner. He needs skill, practice and confidence to calmly deal with the situation.

The AAP encourages parents to consider that starting water-survival skills training at an early age must be individualized, based on the child's frequency of exposure to water, emotional maturity, physical limitations and health concerns related to swimming pools.

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.
