I thought I would be a "cooler" parent. When growing up I was going to be the one that let the kids choose what they wanted to eat, what they watched, etc.
We had kids on the younger side, though not super young (24). So I went from thinking I would be a "fun" mom to not really thinking about kids at all (typical teen, college student, etc) to having kids and being super conscious of everything. From food (nope, they don't ge the crap cereal, they eat as healthy as we ate as kids! my mom was onto something but don't tell her!!) to TV (they do have as many limits as I had).
The one thing I caved on was video games. DH was into them as a kid, and really gets a kick out of the Wii with the little guys. Not huge amounts of time, but I never even wanted one in the house!! We have PS3 too, but no kid games for that, was the only way I was willing to let the hubby get that.
Ah well.....
