My usually dry at night 11 year old son has recently started to wet the bed at night, there are no problems in the home but he is a little worried about starting high school in september and has expressed his anxiousness at this. there is a family history of diabetes so i was wondering if that could be an issue? should i take him to the doctors? I never tell him off when it happens, ive got a plasticised sheet to protect the mattress and deal with the wetting in a matter of fact way but it is really getting him down which i think is exacerbating the problem. HELP!
