In answer to your questions, in advance:
1) No, I did not photograph, said "poo". (My DH's first question)
2) Yes, I make him change his own pull-up. He's plenty big enough.
3) Yes, I've read countless potty training books, and have tried everything ;)
PS does anyone have an inside line on what colleges accept students in "pull-ups" 'Cause I'm starting to wonder......
Knitting update will be posted later;)
