That about sums up what I am doing right now when it comes to these kids. I cannot even begin to count the number of arguments I had to break up yesterday. With Lil' Miss being in school all day and therefore getting a break from Destructo Boy every day I kind of forgot how they often don't get along.
So I am really trying my hardest to not completely lose it and grab their little heads to bang together. I think we may end up taking daily walks to get some of their energy out and just to give them a view other than the house. Having said that I should note it's not like we sit all day around the house! I try to make sure we get out of the house at least once a day, if not to a summer class for one of the kids than on an errand or at least to the park. Even with an outing they still seem to get rather sick of each other pretty quick and end up in some form of an argument, and I only have so much patience for breaking up these daily fights.
One of my tricks to get a little break is to have them watch a movie in their room (yes, I am one of those bad mom's who put a tv in her kids room but at least they don't get cable in there!) while I get to do whatever I want in another room, usually watching a non-child friendly movie myself. Even with that they have still been arguing, over who is on who's bed, over being hit either on purpose or accidentally, it never seems to end. So for now I feel like I am just surviving while I figure out how to keep them happy and busy but not fighting constantly this summer.
