That's a great idea about the mirror!

Both of my kids are different. DD6 used to hold it in until she was so constipated she would cry on the toilet. I actually had to take her to the Dr and get x-rays to show her how bad it was. She goes fine now. DS5 has never had an issue going #2, but he isn't very good at wiping. I'm going to have to look into the mirror idea!
