My 2 year old son hits all the time. He will just come up and slap me in the face or slap his sister's head while she's nursing and kick or whatever. He is just so violent and people are starting to not want to be around us. It isn't the baby I don't think because he's been doing this since last summer and she was only born in November. It doesn't even seem odd to him, he just does it. Oh hello I'll throw a truck at your head. Number one, is he disturbed? I have bipolar disorder and know it's hereditary. Could he have it? Number two, what do I do. I have spanked him a couple of times but I don't believe in it and it doesn't do anything. I tried putting him in time out but he thinks its fun and keeps putting himself in time out now. I've tried talking, making him apologize, explaining, nothing works for this kid. It HAS to stop! I am starting to not like my child very much. Please help me!
