My little girl has been out of nappies for a year now, and has rarely had an accident. In fact the spare pair of knickers I keep at nursery for her has been there for nearly all that time. But now, at 3yrs 8 mths she's started wetting herself every day, usually towards the end of the day, at home & at nursery. The only change in her life recently has been the departure of her best friend from nursery about 2 weeks ago, & we wonder if this is something to do with it. Anyone got any opinions/ advice pls?
