What would my ds who is 2.1 learn at a swim lesson? Surely he cannot learn to swim so young? I am wondering this because ds loves fooling around in the pool and dp suggested enrolling him in a class, but I am worried that it will ruin the hour of fun we have in the water, and that neither of us will enjoy it. Would be great if he learnt to float, do you think he is too young? Any tips?
