Mommy Syndrome

OK so I have been in a mood lately, we can call it mommy syndrome. I am always thinking of the kids and hubby, what would they like? Do they need new clothes? If I see something I know they would like I get it for them or I put into our schedule things they would like to do, even when its the last thing on my list of fun stuff to do. Every mommy does this. We get so wrapped up in their lives we forget that our life is ours too. So I have been thinking of things I might like to have. A new camera would be killer but for what I want, true photography, starting out is $600! OK so maybe an itouch, I can store photos and music and get maps and check my e-mail on the run, $300!!!! For essentially a toy, I have CD players and radios, I have a camera with a SD card, I have the Internet almost anywhere I go. I just can't justify it.
Today I thought I would take Deven out to go get some jeans that don't show off his ankles and I thought, OK I am really tired of T-Shirts and I have about 4 nice shirts, so by the end of the week either I am looking very similar to another day of the week or I am back in a t-shirt! I just want to feel pretty sometimes. So I decided to look for some stuff for me, so after picking out Deven's jeans and letting Dylan get a shirt so he didn't feel left out we went shopping for me.........at least we were supposed to, but the boys kept fighting over who was going to get to push the cart and yelling at each other and generally making pests of themselves. I tried to work through it, used the usual threats, were going to go home, no lunch etc.... but nope, didn't work. So I got to try on 4 shirts and came home with two, a black and a brown, big surprise there, but didn't get to enjoy any of it.
How old do they have to be before I can kick them out??????
