I have a rather unusual problem. My son since about 4 months old naturally stayed dry throughout the entire night. I never trained him to do this but he just did it naturally without any accidents. However, now that he is basically potty trained at 3 years and 9months, all of a sudden he has started wetting the bed. I restrict his liquids at night now and make sure uses the restroom before going to bed and I make him clean up the sheets when he wets but he continues to wet. Before I never had to restrict his liquids. He could drink as much as he liked but he still never wet the bed. I wonder if anyone else has had such a problem and how you dealt with it. For us it is a problem because he sleeps with us.
