My 4 year old grandson has bouts with anger. He hits, bites, spits, pulls hair, throws things, etc. He also tells the ones he loves (mother, grandmother, etc.) that he doesn’t love them or doesn’t want to ever come to their house again. My son and his wife have taken him off of foods that may have an affect on his behavior. They are going Monday afternoon to see if he is bipolar. I pray to God that this is not the case. Is there anyone who would like to discuss this with me? Thanks!!
