My Daughter who is 3 was coming home and playing with her dolls and she was being Penny (her teacher) she would say things we have NEVER said around her. she would yell at her dolls and even spank them. I also had a 3 month old and she would come home with the worst diaper rash during the week! I would have it all cleaned up on the weekend and Tuesday would come around and she would have it again. I don't think diapers were ever changed. I did tell Lauren this and she pretty much told me I was crazy and it was all in my head. I pulled my kids out and my youngest has not had a diaper rash once since then and my oldest is a very sweet and loving teacher to her babies now!
