Oh, classic wondermom... Love it!!.....Don't worry if those guys heard, always remember they go to!!! We are all only human...
Yurt girl, I think if he was mine I would make it so he can't hold, how long does he hold at a time?
He is obviously going though when you say he'll do it on the floor or in his pants, so is he constipated??, I guess you must know the answer to this, how often is he pooing? and is it hard knobs or a nice formed stool?...maybe he has no constipation issue at all, maybe he just has an aversion to the pot? don't know, have a chat with plunket nurse or who ever is your equivalent over there...sound to me like you may have to bribe him to sit...thing is the more pressure they have put on them the more it often puts them off, so try not to lose it, just be as encouraging as you can be...and even if it is in pants etc, it is coming out!!!..reality is that is more important than where, he'll get the go on it all eventually, does he go to playgroups or anything, they often love to do as they see others doing...
There would be nothing wrong with trying a gentle softener, I would suggest you talk to your pharmacist/chemist.
My girl used to hold often 4-5 days, sometimes longer, through the fear of doing a hard poo after having had fissures she knew it would hurt, is it something like this that maybe putting your wee guy off?
All the specialists etc we have seen really pushed the need to sit, and having said that sit correctly, with feet supported on a stool if the child sits on toilet, not dangling in midair, my girl is tiny for her age, and still actually fits and sits on a potty, she is 5 1/2,and yep this is fab for her as her legs are parallell to the floor etc.
It puts the pressure going in the right direction etc and really opens the way for that movement to take place.
Having told you this I realize, very much so, that you can't make them sit if they don't want to.
K went for many months not sitting for poo,mind you of course she had no idea when it was there anyway,(encopresis kids loose all feeling of poo) but she would only sit long enough for pee.She would poo at weird hours of the night obviiously after she was relaxed enough and had no idea, she'd then yahoo out to me, I didn't care at least that was another one out!
