In the past, the AAP advised against swimming lessons for children ages 1 to 3 because there was little evidence that lessons prevented drowning or resulted in better swim skills, and there was a concern parents would become less vigilant about supervising a child who had learned some swimming skills.
But new evidence shows that children ages 1 to 4 may be less likely to drown if they have had formal swimming instruction. The studies are small, and they don’t define what type of lessons work best, so the AAP is not recommending mandatory swim lessons for all children ages 1 to 4 at this time. Instead, the new guidance recommends that parents should decide whether to enroll an individual child in swim lessons based on the child’s frequency of exposure to water, emotional development, physical abilities, and certain health concerns related to pool water infections and pool chemicals.
