N.B.
I wouldn't worry too much. I just got my 3 year old son trained. My husband was in Iraq and he would go for everyone but me. He wanted to go potty like Daddy, so when daddy came home he took a big part in the training and he got it in about 2 weeks. They just have to be ready to do it. Don't stress out about it. I didn't think I would ever get my little guy trained, but it happened in HIS time. I would also set his potty chair in front of the TV (not the best idea with boys) and he would use it . Once he got that down then it was moved to the bathroom. Now he stands up to pee and has a better aim than my husband most of the time.
