Yeah I did the same ^^^.
My now 6yr old lad (birthday today!) would wet himself all the time with the pull ups. In my opinion, pull ups are the worst invention ever! Cos they give kids the impression that it's ok to wet your pants :/ I did the letting him pee in his pants, he quickly cottoned on and didn't like wet pants and started using the toilet.
Long story but when my eldest step daughter was in foster care when she was 5yrs old, she started bedwetting which is understandable in the circumstances, the foster carers put her in pull ups and the results was disastrous! We finally got her toilet trained at 7yrs old and even now at 10yrs old, she isn't bothered at all if she wets herself (which she does on a regular basis). We have tried everything possible to get her to stop wetting herself but she isn't embarrassed about it at all. She could not care less at all - her attitude is like "its fine to wet myself so i wont go to the toilet tll the last minute and who cares if i dont make it in time!?"
I blame the pull ups, the carers should have left well alone and the bedwetting would have stopped soon enough by itself.
