We started taking Olive at 7 months. We started at the SE Community Center. Our Dr. told us that it was a lower chlorine pool (or at least not as much as some of the swim schools). We loved it and took her back at 10 months as well. It's a super nice pool with family changing rooms and the teachers were all really great that we had! Relatively affordable too. I think it was around $40 for 4-5 weeks at twice a week. The first sessions we did every week night for 2 weeks straight. They were both good options but I think going every night was a little bit of a burn out for me...the class was right around "dinner time." Anyway, check it out! It's a very nice center.
