Is this possible? My 3.5 year old girl has just started 'leaking'. She wets her knickers 5 times a day even though she's been fully potty trained for 8 months day and night. She doesn't do a whole wee, just a little. And not because she doesn't reach the loo in time, just ad hoc. It just started one day and has been going for a week now. Reminds me of stress incontinence. Anyone else had this? Any advice? She keeps getting sore from keeping wet knickers on at nursery where they can't monitor her constantly like I can at home.
