Our son started swimming lessons this past summer and his instructor also works indoors in the winter borrowing space from aquatots. It has strengthened his core and improved his confidence. I found an instructor through our local autism community that works specifically with kids with learning differences. I hope you do it!

My twins take swimming lessons in the summer at our local Rec center and I see older kids learning all the time... I would go for it, the rec lessons are way cheaper than all the others around here so if he isn't ready it won't be a huge expense of you have a rec near you...it is $40 for a two week program here...this year, I'm signing my twins up for two so they'll have a month of lessons
