DD is 2y9mo. She's been potty trained (daytime) for about 6 months (barring the odd accident). We moved her into a bed a few months ago (DC2 due in 3 weeks).
For the third night in a row, she's pooed in her nappy within an hour or so of going to bed and then called for us. She then shows us a little display of poo that she's arranged on her bookshelves... and asks for a new nappy.
Just before we moved her out of her cot bed, she had started sometimes throwing poo out of her cot in the mornings - one of the reasons we moved her, so that she could use the potty if necessary.
Some nights, she has taken off the nappy and used the potty properly, calling for help afterwards, so she does know how to do this. occasionally there have been smears on the wall - I think where she has been trying to wipe it off her fingers.
Obviously we encourage using the potty before bed, which she will sometimes do.
Any experience of this? Helpful suggestions of how to tackle it? At the moment we are being low key but disapproving.
She is a delightful child really...!
