My kids look lessons at age three and the other at 18 months. I did a mommy & me class with the 18 month old and we actually had her doing the backstroke very well. I would start the lessons now if you can. Why wait? We loved the Hubbard Family Swim School. They have a location at 32nd St. & T-bird and also at T-bird and 83rd Ave. They do a great job of doing drills having the the kids jump in and floating and also swimming to the side in case they fall in. I highly recommend them.
