My DD is 3.5 and has been daytime potty trained for 6 months. But she still has to wear a night nappy and she will until she is reliably dry at night. Anyway, when I get her up in the morning she always has a poo in her nappy. She has been reliably doing wees and poos on the potty in the day until recently, and wears a pull-up in the day. But I don’t know why she suddenly started pooping in her nappy in the morning. What should I do? She has also had a streak of number 2s in her pull-up over the last 2 weeks. Should I put her back into nappies in the day for two or three months and then try again?
