Refusal of pooing on the toilet. Advice/tips welcomed!!

[Elmo20]

My daughter mastered potty training very young, before she turned 2 - all was going well until Christmas time when she became constipated and passed a really hard and painful stool. Since then she has been refusing to go on the toilet for poos, withholding it for days until she loses control of her bowel and souls herself. We have just done the disimpaction treatment using Movicol and are currently trying to find our maintenance dose. She still refuses to use the toilet or even tell us when she needs to go. Only letting me know after she has pooed in her knickers. She acknowledges that the poo is “nice and soft” and doesn’t hurt but I can’t get her to sit on the potty or toilet without a meltdown. (She will happily sit on there to do a wee - it’s just poo she has an issue with)

I’ve tried encouraging her with incentives but she is just not interested. How do I get her over her fear and going on the toilet?! Any advice/tips will be greatly appreciated.

Very similar story to my daughter; she screamed and got really angry when I tried to encourage her to go. Our paediatrician has put her on Pico Sulphate (as well as Movicol) which stimulates the bowel to push. It has improved things and she now runs to the toilet saying she needs a poo. We’re not totally out of the woods as we now have more soiling and daily diarrhoea at the same time so I’m looking for more advice on that front. Have just bought the book “The ins and outs of poop” by DuHamel on the recommendation of another poster.

I’m having pretty much the same issue with my almost 3 year old. He’s taken to hiding in the summerhouse when he needs a poo so there’s a potty in there now and I’m hoping he takes the hint 🙄
