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.
We can't tell a parent or child exactly when they're going to learn to swim, Williams said. It's a learning experience in and around the water.. The Red Cross has a similar approach. Though its parent-and-baby classes start at age 6 months, it doesn't start teaching kids to swim solo until about age 5. But at Swimtastic Swim School instructors teach classes for babies 6 months to 2 years, with the goal that they swim 5 to 10 feet independently by the end of the advanced course.
