My grandchildren live with me. This is their second year. This past year my granddaughter began terrible anger fits and throwing things at me; refusing to do what I say. She also is wetting her clothes any time she wants during the day and night. She is 6 yrs old! She and my grandson have been in therapy for almost 2 years now. She has permantly ruined her clothes with the urine smell to the point that her clothes have to be washed by themselves. I am at a loss to know what to do. The doctors have put her on a low dose of prozac and a sleeping med to help her sleep. If she doesn't sleep, she wonders around the house and tears up clothes left out. I guess my question is, why now and what can I do to help her?
