My son started swimming lessons when he was 6 months old. I remember being extremely excited about enrolling him in his first “activity,” but that all faded when he had no reaction to his swim class at all. He didn’t cry, but he definitely didn’t smile. He was unsure about the whole situation! His eyes were huge and he looked shocked during the whole first class. Like he wanted to say, “Mom, where are we and why is it so loud in here!” It took him a while to really enjoy swim lessons. He was a very quiet, calm, and shy baby.
