What to do?

I think every family has that one child that is out of control. That nothing you do helps their behavior. Well we all know Parker is that child for me. Don't get me wrong I love this child. He loves to kiss and cuddle with me.
Parker was a perfect baby, seriously perfect!! It all started when he hit a year. He became mobile and started the hard stage way earlier than any of his older siblings. It frightened me to think I had to deal with this so soon. I was hoping since he started it earlier it would end sooner, but it is still going and even stronger than before. Parker is always on the go from the time he wakes up(which was 5:20 this morning) to the time he goes to bed. NONSTOP people! He makes me tired, really tired. If you don't hear him he is doing something naughty. Like a couple days ago when it was way too quiet and I looked in the playroom and found this:

Luckily it was washable but the marker he wrote on his new bunk beds with isn't. We only had them 4 days and he did that. See where I am going with this? We have tried everything with him. Time out, in his room, spankings(he just laughs at us), filling up a jar with marshmallows(he gets a toy if he fills it up), chore charts. Do you see why I am the counting down the days until he goes to preschool? His new thing the last month has been to be mean to Noah. Not just a little push. I'm talking biting, hitting him hard in the face to where he has a big red mark, pinching, jumping on him. Poor Noah is so scared of him. I can't even leave him alone for a minute because I don't know what he will do. The other day he sat on Noah's face. He sat hard and for a long time. I had it with him, so what did I do??? I sat on his face and asked if he liked it. I'm sure some of you are shaking your heads and thinking I am a terrible mother. You might even be thinking of calling CPS. But guess what? It worked! He hasn't touched Noah since. I think every kids is different and they all learn in different ways. Parker needed to know what it was like for Noah. See no one touches Parker because he is a tough boy and strong. So he rarely gets hurt by the other kids. Hopefully he will just laugh about it 20 years...hopefully.
