Children between the ages of 6-12 months old are taught to roll over and maintain a back-float position in the event of an accidental fall into the water. Teaching your infant to float takes approximately 4 weeks. Private 10 minutes lessons per day are held 5 days a week, Monday through Friday. Skilled infants are taught to maintain a back-float in a bathing suit and in clothing. If you own a hot tub, pool, boat, or just enjoy the water, ISR highly recommends survival training once your infant begins to crawl.
