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.
Babies who begin to learn to swim between the ages of 6 months-18 months old will take around one to two years to learn to be safe in the water. Children who start swimming lessons between the ages of 18 months-3 years old will take about one year to learn to be safe in the water. Children older than 3 years old with no previous swimming experience will take about 6 months to one year to learn to be safe in the water. With group lessons, the process of learning to swim is slower. The sooner your child begins to learn to swim, the sooner your child will be safe in the water.
