The little girls...well they will be in level one yet again next summer. BUT! I think they will get through it fast though, because they only had two things to work on and they are actually swimming by themselves for the most part. Lana can even do arm over arm or "ice cream scoops" as they call them.
I know some kids jump in the water and are swimming within a few months. Mine are taking the long road. The one that takes at least four years to learn to swim well. All that matters is that they end up in the same place, being able to swim on their own. That way Mama can sit beside the pool and read a book while they play at the pool. I feel like I might be only one summer away from that dream!
