Week 67: New swimming tool and potty training progress

Last weekend we took Sophia to swimming class. I bought new floating swim gear for her in Paramount Sport Center. One is to put on her arms and another one is to wear over her chest. We took the one on her arms to the swimming pool. She doesn't like it at all.
Over the weekend, her potty training got progressed. She wore one pull up diaper from 3:30 PM to 9 PM. I took her to use the potty every 45 minutes. The pull up diaper was dry before she went to sleep. She got the idea to use the potty when she needs to pee. It will take some time before she can go to potty on her own. Given she is only 15 months old. It's a good start.
