Have contributed elsewhere (still getting the hang of this talk business) but am looking for advice on what to do with dd1 who's 4.5 years old and has just started wetting and pooing herself again and refuses to go to the loo even when it is blindingly obvious she's desperate to go. Have been angry, have been nonchalant, have a star chart - nothing seems to work for very long. She only got potty trained after a long hard slog and lots of bribes. She's still in nappies at night. Any tips?
