A.D.
L. - I know exactly how you feel - my daughter was potty trained - but would NOT poop in the potty - she would to to the closet - put on a pullup - go to the bathroom - poop in the pullup and then come and tell me she was done and needed to be cleaned up - I'm laughing about it now but at the time it was SO frustrating -
I spoke to the pediatrician about it and he said 90% of the questions that come into him have something to do with pooping in the potty:) - he went through it with his own son -
what he said was just let it go for now. The more you focus on it and bring attention to it - the harder and longer it will take - Something will click with your son - and he will go!
The doctor told me he offered to give his son a prize that he really wanted if and when he pooped in the potty - yes it's kind of like bribery but it worked for him!! I tried to do that with my daughter and it did not work - so I just let it go and a month or so later she just went on her own and the rest is history!!
Hope that helps.
