They won't leave me alone, then when I tell them to leave me alone or go and play in their rooms, they get into stuff that they KNOW they aren't allowed to touch. They drive me nuts, what do I do? How do I get them to leave me alone, and not get into stuff? I could pull my hair out sometimes with those two.

I have a 2.5 year old that doesn't really like to play independently so I set up activites for him in his room. I usually put out things that he really likes so he will be excited about it and not pissed because I'm not playing too. Some things he likes which may not apply to your kids at all are play dough with a rolling pin and plastic forks, clear disposable plastic cups each filled with a different color of water made with food coloring( put out turkey basters, empty containers, or clean medicing syringes without the needle of course), and a small margarine tub with a 2 inch slit cut in the lid and poker chips that are big enough to not be a choking hazard. Another thing I do to keep my son busy is set up craft projects or games in paper lunch sacks so all I have to do is hand him the sack and he can do the rest. Some ideas of what to put in the sack which again could be inappropriate for your kids depending on their personalitys are glue, small pieces of paper, scraps of foil, string, and a regular sized piece of paper. Sometimes I'll just put a few of his fav. toys in a bag and when I bring them back out again he gets so excited. If all else fails take them outside. My kid leaves me alone for an hour if I take him outside.
try a movie, or wiat till they go to bed
