My daughter is turning 8 in a few months and still won't poop in the toilet. She is ok with wees during the day and has been day trained since around 3ish. She used to suffer from constipation when she was little and that isn't a problem anymore. She will only poop in a nappy or pull up. She is still wet at night so wears a nappy to bed . So she mostly waits until night nappy is on and then goes in it or she will go first thing in the morning in her nappy. We have tried rewards bribery and taking away the nappies but she will just hold it for days and make herself sick. We can't even get her to sit on the toilet with a nappy on which is what her paediatrician advise us to do. She has no other issues aside from being very stubborn and sometimes defiant. My husband and I can't even have a few days away without the kids because his mother refuses to change our daughter when she poops. And our daughter will only let my husband and I change her anyway. I feel like a failure as a mother and don't know how to fix this. Most people I know who have kids who refuse to poop in the toilet their kids work it out by 5 or 6 at the latest
