My daughter, 2.7, has been wet potty trained for a few months now but refuses to do a poo unless she's wearing a nappy. For half an hour before her lunch sleep I alternate between sitting her on the potty and the toilet while saying that poos like to go in the water and go for a ride when the loo is flushed. She will not produce anything but within 2 mins of having a nappy on and being in bed she's calling out that she's done a poo. I've tried not putting a nappy on her for her sleep but this just stops her sleeping. I've tried not putting her down for a sleep but this just means that she won't poo until she goes to bed at night time which can't be good for her as she obviously needs to go because she spends the day farting! Has anyone found a way to change this or is it something I need to leave and hope it she sorts it out in her own time?
