You might want to check your local YMCA. Most offer swim classes for kids as young as 6 months old. I take my 3 1/2 year old toddler to the YMCA in West Chester. He started swim lessons there when he was 6 months old and has been going there ever since. I know that there is a YMCA on Rt. 1, not too far from Media. I think it's called the Rocky Run YMCA. The YMCA swim classes for kids under 3 usually require that the parent is in the pool with the child. Once they turn 3 they can do the classes that don't require the parent be in the water.
