Dear mikkel,From what I have read you have told us your child had been a heavy bedwetter ever since he was born well there is nothing unusual about that!the majority of children wet at night and gradually stop when they are older I stopped when I was 17! however he is now having accidents during the day and messing you say you have put a nappy on him when he is out on journeys and when at friends and you are considering putting him in nappies 24/7 wellI feel like the other Tom You should wait and see what the results say as there is such a thing as conditioning which as you have been putting on a nappy when he is on journeys and at home hyou are conditioning him to accept this it is a known phenomenon it could be lazyness holding back until he has to wet and witholding his phesis because he is so engrosed in his play that he forgets until its too late !putting a child back in nappies 24/7 is a very drastic thing to do i would if the results come back negative and all is well i would suggest you consult a child psychologist who deals with theses things he may well tell you to put him back then re-potty train him! best wishes please let us know how you do get on! best wishes, TOM.UK
