Trying to get my 3 year old out of pull-ups before he starts preschool. Whenever we are at home or at someone else’s house without a pull-up he has no accidents always tells me when he needs the toilet. When we are in the car or out and about i.e soft play/ shops/ park he wets himself every time even though I constantly ask if he needs a wee i’m stuck as how to get past this he doesn’t particularly care about being wet just carries on so now we’re in the habit of putting on a pull-up whenever we go out anywhere… any advise please??
