Have there been any major changes in your daughter's life that might be stressful or upsetting to her? New school? Problems at school? New sibling? Problems with your marriage or a divorce? There are many possibilities that can have an effect on a young child including the onset of bedwetting, even though the child may have been dry for years. There are some who post on this board that have experience in these areas. Perhaps they can help shed some light. How is your daughter otherwise? Does she seem changed in any way?
