I need to say a big THANK YOU to you for a long detail information. Deeply appreciated. This info. helps me a lot on toilet training. I don't know is lucky or not, I was very seldom to deal with non-potty trained kids. Now, i feel more confidence, when i need to talk to some parents whose kids are not potty trained. May I have your toilet training guide sooner than later. I am starting to interview with some parents soon this and next week. Sorry for asking you again. Thank you again!
