People with Marfan syndrome may have: 1  A tall, thin build. 2  Long arms, legs, fingers, and toes and flexible joints. 3  Scoliosis, or curvature of the spine.  A chest that sinks in or sticks 1  out. Crowded teeth.  Flat feet.
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.
The American Academy of Pediatrics supports swimming lessons for most children age 4 and older. If you enroll a child younger than age 4 in a swimming program, pick one that requires parental involvement, has qualified teachers and a fun atmosphere, and involves a limited number of underwater submersions. This will limit the amount of water your child might swallow.
