Hi from another first timer and I too am so glad I found you! I really do not think my issue is related to constipation as he can do 3 a day (his fathers son....) - not sure if the problem is laziness or fear or it's just a boy thing and he'll get over it, but not sure what I can do to break the cycle.
My DS is 3 1/2 and I didn't rush ptty training - I started at Xmas, and after the initial clueless few weeks, he is now a star with wees, will take himself off on his own to the toilet for a stand-up wee or potty if he has left it a bit late - very few accidents - good times. But he is a total nightmare with poos - bad times. He just will not do a poo on the potty or the toilet. Like many others I have been reading about, he will hide away, and do it in his pants or his pjs, which being looser than pants means that the poo falls out of one of the legs onto the carpet - nice touch... He then wants to clear it up and put it in the loo and flush it away, so he is not frightened or offended by poo. He just hides away when he wants to do one. He is at nursery 3 days a week and they say the same - he hides away. Like I have done at home, they have worked out when the popular poo times are, and encourage him to go on his own, to go with his chums, and regularly ask him, but same as with me, 2 minutes after sitting on the toilet, he will then hide away in a corner, under a table and do it in his pants.
When I see him doing it - I know the signs now, oh boy I know the signs - I try and get him to move, but he refuses, gets upset and distressed, and not wanting to make a big deal of it, I don't force it. If I know he has done a poo in his pants (he never comes and tells me he has done it) I have tried all the approaches; no reaction, casual reaction, cross reaction. We have tried treats, rewards, taking away toys and currently the penalty is taking away favourite pants, but nothing seems to have any impact. He really doesn't seem to care - probably because mummy does.
Yesterday he was having a nudey run around in the house, and he happily pooed on the carpet just in front of me when the potty was almost next to him. Try and stay calm when you see that happening. He then wanted to help clear it up.
He knows it is wrong - he regularly says "we don't do poos in our pants do we mummy, we do poos on the potty or the toilet..", but so far lots of talk but no action.
So, I have read your advice above neolara and I am going to give it a try. I am really bored with it, and whilst I am sure that one day, like the wees, it will be okay, I want to try and help him get over what seems to be a phobia of pooing on the potty or the toilet. The other day I did manage to get to him just in time and got him on the potty (with a bit of resistance, but he wasn't distressed), and I stayed with him and he did do a poo and you'd have though I had won the lottery by the level of clapping, cheering and whooping that could be heard from our house with the pair of us jumping up and down with delight!
I feel better for my rant and it is really good to know I am not alone in my pooey pant hell!
