Last year Liesl started to swim back and forth between Jason and I so, I was sure she would be swimming this summer, but she wan't ready. I tried to get her to swim without the arm wings and she did a few times, but not for long. Well the other day at my parent's house she got out of the pool and said she was ready to swim without the wings. She took them off and started to swim. I showed her how to lift her head to take a breath and now she is a full on swimmer.
