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.

Everyone needs a little break from learning to process the information and in this case to give muscles a chance to recover. In addition, you need to be able to spend time with your family, as does your instructor. Weekends are family time. Periodically, if weather or other issues have cause lessons to be canceled for numerous days, your instructor may choose to offer make-up lessons on a weekend. This is strictly up to the instructor and based on the availability of parents.

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.

ISR instructors teach infants to swim by honoring each child's individual strengths and experiences. They understand the fundamentals of the behavioral sciences, child development and of sensori-motor learning as it relates to the acquisition of aquatic survival skills; they use this education to guide each child through the sequence of learning to swim and float.
