My non cah son wets the bed he is 4. I have to say that I too was a bed wetter. They just grow out of it. And it hurts to make a big deal of it. We got large diapers and put it on him at night and in the morning he say who put this diaper on me. I dont think it is cah med thing. Just part of growing up. Thank you Mother P.S. My husband was dreaming one night that he was peepee in the tiolet but he was in bed. HA HA I was a bed wetter.
