Since 1966, Infant Swimming Resource (ISR) has been the safest provider of survival swimming lessons for children 6 months to 6 years of age. Starting as early as 6 months old, these lessons focus on teaching the child to roll onto their back to float, rest and breathe, and to be able to maintain this life-saving position until help arrives. Kerri uses the behavioral sciences: sensorimotor learning, positive reinforcement, and operant conditioning with your child. The program focuses on survival swim, but children who can walk (generally one year of age and older) will learn to swim during lessons.
