First you wait until he does the unwanted behavior. Then you take a chair. Pick him up and sit him on the chair and firmly instruct him not to get off. Everytime he gets off you put him back on. It's a pain, but you won't have to do it for long.

You put him there for one minute for every year he is. To a two year two minutes seems like a long time. Each time he does it you quickly do the same and in a day he should get the idea that you are not playing a game.

At his age telling him you are sick or not strong will mean nothing. He won't get it. You are still in control and you are the boss. I know it feel awful to feel at the mercy of a child, but just wait until they are teenagers.. Good luck!!!!

I've got an old electric cattle prod that was used on the farm to encourage calves and cows to move along with an electrical shock. I could loan that to you ;-)

You tell him he needs to stop now. Have him sit in a chair and talk to him about it. Tell him he cannot do it anymore or you won't be able to care for him..If he continues have him stay in the chair longer. If he continues send him home.
Find something fun to do apparently that has gootn him some kind of attention somewhere along the line.

I hear you.

My kids are two boys ages 3 and 6, and what an active bunch they are. Jumping on mama is super funny to the 3 year old. Sometimes they get so wound up that time outs and firm voices don't have any effect.

Are my kids out if control? Nope. Because these are the same loving boys who tuck mama in at night sometimes and gently pull the sheet up over me to tuck me in.

One thing that works is when they have a lot of energy to get out, I take them someplace like a park where I can sit in a comfy chair (I keep one in my car) while they play on the playground equipment.

Otherwise no easy answers.

I don't have any kids so I'm not much help. But I really liked Russ answer that was funny thanks Russ. I'll have to remember that when my wife's grandkids come over. I do have one idea I used to work in adult corrections and if they were good I let them watch TV if not I pulled it out of the wall and put it in my dorm office.

Haaaa ha ha ha! That works for kids too. Sometimes they are a little like convicts!!!!

Hey it worked for me when I was healthy and I walked in the dorm it got quiet or my office was full of TV's. Maybe that is what you need to do find the trigger item that they cannot do without.

Another place to take them is a McDonald's playland. Other kids to play with, air conditioning, and a built in place for you to sit. Just remember that they have to wear socks, or you have to buy some (at least up here).

Thanks for all your advice. While the cattle prod sounds fun, I get the feeling that might be a bit too extreme :P. Thirteen and Ann, I think your advice is what I'm going to follow. They are finally home so I get to rest up, but I am positive they will be back at some point this weekend or next week, so I want to be ready. Normally I don't mind him playing around. He likes to fight and push around and my sister allows it. So I just go with the flow. But him knocking me over, that is very unsafe for me personally, so I am going to talk to her about it too in my spare time. I'm trying to find a good way to talk to her about it, as she can be a hot head about things like this. A simple inquiry can turn into a knock out drag out fight if you get what i mean. Thank you all for your advice, and suggestions. It feels really good to learn these things. :)

As a side note, isn't it amazing that you can get so weak that a 2 year old has the strength to push you over? As much as it sucked, I did find it interesting that he had enough strength to take down a 280 pound man, and he weighs like 35. Oddities of my mind. :)
