The new guidelines, however, do not extend to all children under 4. The AAP still does not recommend swimming lessons before age 1, and says children with motor or cognitive disabilities may not be not be ready for swimming lessons until a later age. Drowning is the second-leading cause of death for children ages 1 to 19, according to the AAP report.
SWIM LESSON TIPS: 1  Each swim lesson for infants and toddlers should last only 15 minutes; up to 30 minutes for 3-5 year olds, and up to 45 minutes for children over 5 years old.  The ratio of swim teacher to swim student should be 1:1 for children under 5 who have not reached swim stroke and treading water proficiency.
