Swimming Lesson Set Backs

We started swimming lessons again two weeks ago, and for some reason Parker is 0 for 2 when it comes to having fun. He used to loooove swimming, but for each lesson he's been REALLY clingy and cry-y (which is odd because he rarely cries). I'm still not 100% sure why but I think it's because there's also an open swim at the same time as our class and the pool is a total zoo. It's really loud and chaotic (when it's normally pretty quiet) and I'm thinking that might freak him out a bit. We're going to keep it up, though, and hopefully he'll be back to having a good time next week!
