last year we got him in ISR classes, he was 2 1/2 and these classes are for survival. She taught him how to float, swim, float and to get himself out of the water, if he were ever to fall in without us around. The final test was for him to go in fully clothed in summer and then again in winter clothes...shoes, socks, shirt, pants and coat. He did great. He went under and then immediately came up floating with a smile on his face. NOW, he is able to swim, dive and jump in our pool. We are so greatful for the ISR classes and added safety we also put a babyguard gate around our pool. this is always up unless we are swimming. He floats better then I do hahaha
