DD is almost 4 and we continue to have ongoing problems with knicker wetting. It's been on and off for months, and I don't know how to deal with it any more. She is dry more days than not at nursery (but probably has accidents once a week), but we get lots of accidents at home. We've tried taking away favourite things (mainly watching Octonauts) and reinforcing positive and rewards for a series of dry days. I've tried asking why she doesn't but don't always get an answer, sometimes she seems to know she's wet herself, but other times not. I'm out of ideas of how to deal with it. Any ideas welcome.
