My DD is nearly 3.5 and has never been totally dry but lots more accidents over last 4-5 months. Tried all usual rewards, regular reminding etc. Been to HV and GP, urine tests clear. Kidney scan due to various family oddities suggests slightly immature bladder muscles but not v conclusive. Regularly wetting (2-3 times a day) at nursery(pre school state) and childminder. In all other respects she is happy and developing v normally. What to do next - nappies? further tests? Also increasingly worried as nursery and childminder v understanding so far but how much longer can we expect them to keep on changing her?
