Hi M.!
I don't have my 2 1/2yr old enrolled in swim lessons yet, however there is this place I got a flier from called Aqua-Tots. It would be like $100 a month but that is for 2 days a week for 1/2hr or so. Its indoors too which I like in this dang heat! I hope to get my son enrolled in January.
Good luck. Here is the website www.aqua-tots.com
