I think a child develops they're individualism in the first 5 years from they're parents...they watch, study and parrot. So, if the mother is so over aware of her looks, clothes, etc...so will her daughter be...and my son has been away, therefore, my dil right now, is her only influence, and she will be 8. There are indeed other forces at work...however, at such a young age, I do believe parents are the biggest influence...and please feel free to contradict me...surely, I could be wrong.
What worries me, about this is, what if my GD marrys someone who isn't making good money, and she decides not to work, but expects everything extravegant in the way of clothes...make up, nails, hair, etc....it's not a good thing...she's used to getting it now, and she will believe that it's normal...plus, I feel while she looks stunning, and adorable, my GD will have a hard time in school, b/c she's over dessed and the other kids will mock her. Also, you know how jealous girls are..it also makes her a target.
Now, I could be wrong, and really, this is none of my business...besides, in every other way, my DIL is a fantastic mother, so this may be a little thing? But it does worry me.
As far as TV...I really believe over the years, it does have a huge influence on conditioning people to believe, act and feel as they do. I'm totally there with you on your feelings...have you noticed those reality shows actually encourage people to fight with one another, to call them names, to be dishonest...etc...and they call that entertainment? Sheesh....
What really angers me, is, the Bachelor and bachalorette?

All these people they date...they kiss, and sleep with, and then they pic someone?

?? Sheeesh? I wouldn't want anything to do with it...and think very little of those that participate....especially that one who was a father? How shameful.
