DEAR SADIE YOUR BEST bet is to tell your Mum if you are closer to mum! or an Aunt you feel you can talk to! wait until you are alone and she is not busy ask her if you can talk to her in private say to her I have accidentally wet my bed quite a few times !and I need help!. probably she will take you to the doctor and have you checked out for any problems medically if its a matter of you sleep to deep then they will sort things out be brave ! Your mum probably will already know as if you have wet it badly pee smells and mum will probably have noticed !a plastic sheet underneath will be best to protect your bed! but if not then i suggest you tell her! hope this helps you !
