Many thanks for your response!
My son doesn't form normal stools, it comes out as a slurry - a thickish, blackish paste. It's very sticky so there's really no possibility of him learning to use the toilet while it's like this. This is quite common for a child born with Hirschsprung's, in which the "dis-eased" or aganglionic bowel is removed so the functional bowel can be reattached to the anus. We're told as he gets older (possibly school age!?) that his bowel will adapt and a new rectum will form, allowing stool to accumulate and form a proper poo! {The tendency then is for children to develop an underactive bowel causing constipation.} Anyway, I'm really interested in EFT to facilitate this adaptation, but without any real understanding of how it can be applied (for example, what emotional issues others have focused on in similar situations). I guess I'm hoping that it's not just a simple physical problem, but that there are underlying emotional issues that when addressed may be helpful.
