She was potty trained at 2, we've had a few relapses since where getting the star chart out sorted it, but this time nothing is working. Tried getting cross and taking her favourite stuff away, went back to the stars with a big present promised...nothing working this time. Today my tactic was to ignore it and leave her in her wet pants and she has weed herself all day, pants and shorts really stinking tonight. Can't carry on doing that. MIL says put her in a nappy. Don't know what to do, don't understand why she's doing it, nothing major is going on - any help gratefully received!
