Playing in the toilet

I was here in the kitchen cooking and suddenly I heard our bath room door open. I hurried to check who was there and I saw my pretty daughter Elizabeth playing in the toilet. My husband forgot to lock the bathroom door. Every time she knows that the door is open she goes inside. That is what happened last night too she was playing in the water because I too forgot to lock the door. My daughter is very quick I think when she knows that we are busy she checks the doors and if she get a chance she will sneak in our bed room and you will see her on top of the night stand it scare me every time she does that. I really need to stay more alert in watching them.
