when should I sign my son up for swimming classes ?

He's just turned one and i don't know if now is too early or if I should wait? Can he actually learn to swim right now or is he too young? I was going to sign him up for mommy and son lessons but I don't want to waste my money if it's too early. We have a pool at home so I think it would be useful.
