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.
When your baby is 6 months old, you can join a parent-child swimming class. You'll be in the water with your baby during these classes, which are opportunities for her to be around other babies and become comfortable in the water â not learn true swimming skills. Your child probably won't be developmentally ready for formal swim lessons until age 3 or 4, at least. The American Academy of Pediatrics (AAP) says classes for children younger than 4 can be enjoyable and helpful but warns that many parents may become overly confident about how much their child learns in these classes.
