Will try to keep as brief as possible.
DD1 is 3, she has been out of nappies since 2.5yo and hasn't had one accident - her bladder control is truest remarkable - BUT she won't poo in the toilet come hell or high water. She will only go in a nappy.
Back story : she was badly constipated when she was 2 and as a result started stool withholding. It's an on going issue but she's on Movicol daily which has made her regular and it's no longer an issue having a bowel movement , as long as she has a nappy on.
The problem is, she will literally just hold on to it until medical intervention if I don't let her poo in a nappy.
What is the best way to tackle it??
Any advice welcome
