I have a 5-year-old difficult child who has lots of aggression, anger, social skill problems. No one in my rural area will see her until she is 6. A friend did some research and said that GABA is supposed to be good for such children. Does anyone have info on this? Also is Mellatonin safe for her for sleep? What about my 9-year-old difficult child with ADHD who is currently on Ritalin? Can he take Mellatonin? I'd sure be grateful for any input!
