my eldest is nearly 12 and is still not fully toilet trained. In so far as he soils his pants at night. other than that, he wees fine. He doesn't wear nappies but he does poo into his pants several times a week. luckily, he only ever opens his bowels in the late evening, so it's not something that affects him at school.
My youngest (10 and a half) came out of nappies before he was 6 and he's not had any soiling problems. Sometimes he has wet or soiled himself because he's been engrossed in something and not prepared to go to loo
but nothing like my older one, who I am convinced actually has a physical bowel problem. Will anyone listen to me? will they bollocks.
They were both still wearing nappies at 5 & 6. one morning I took the wet nappy off my youngest and put a clean one on. he took it off, threw it across the room and never wore another one! My eldest then didn't want to wear nappies because the younger one wasn't, but tbh, he really should have carried on because he still soiled. I think he still had to wear nappies at night for a bit longer. but he kicked up such a fuss that we let him go without in the end.
We never forced it. Well, I tried at normal potty training age but quickly realised that was the wrong approach. so we just made potties available, made sure they knew what they were for (neither of them were particularly verbal at the time either so not talking about it!) and waited for them to be ready.
