When dealing with bed wetting I did everything I could to not fully wake up while I dealt with the situation. With this system I had everyone back in bed in three minutes: When making the bed initially, put a "disposable underpad" on top of the mattress pad. Put the fitted sheet over the pad, then the flat sheet, a soft/comfy blanket, and then a comforter or another blanket if need be. When they wet the bed, as long as everything went down and the flat sheet and blankets are still dry pull them back to the end of the bed and take off the fitted sheet and pad. Throw the pad away and put a new one on the bed. Here is the secret: simply pull up the FLAT sheet over the new pad and put the pillows on top. Have the kid, who is now in dry undies and jammies because they changed while you "changed" the sheets, climb back in on top of the flat sheet and cover them up with the comfy blanket. They won't miss the flat sheet on top and you didn't have to completely strip the bed and fight with a fitted sheet in the middle of the night. Wash and fix everything in the morning, and keep using the same pad until it gets wet.
