I'm 23, no children, no hubby either, but I'm actually finishing the first semester of my Master's program in school counseling.

Sure, talk to your counselor. They are there to help you and listen to you. But if your counselor is anything like I'm being trained to be, they don't give you answers or advice typically. They listen and ask questions in hopes you can come to your own solutions. Or at least that's how it's supposed to go, per the ASCA National Model... Ahem. Yeah, I'm still in midterm mode, so ignore that part of my post.
I think it is important to limit the time children are online. The computer's a great source of entertainment and information, but it can become any of our only source of fun and info, and that's never good. Because I'm in grad school, I feel like my computer and I are attached at the hip, to the point where I'm thrilled to get away from the darned thing and the internet for just one day.

I didn't even have a computer until my senior year of high school, and I was not allowed to have internet access until the summer before college. Yup, you read that right. No AIM, no online games, no email. I remember friends talking about IM and my response was "What's that?" And again, I'm not 95 years old! I'm 23.
My point is, as little as they make sense to some of us at the time, most decisions by parents are well thought and have your best intentions in heart. I hate to use the old phrase "It'll make sense when you're older," but it's true. Enjoy the non-computer dominated life while you can, lax. I'd give anything to have more time to read what I want or be outside in the nice weather.
