Let me help you here: The word you are looking for is "No".
I have a 10-year-old daughter. I retain veto power over what she watches, which clothes she buys and what she can do on the Internet.
She wanted pierced ears because "All the other girls have them!" I told her "no".
If she wants to buy "sexy clothes" because "all the other girls wear them!" I tell her "no".
Will her self-esteem suffer horribly because she doesn't conform to the mistaken notions of a bunch of other children? Hardly.In fact the opposite. She will learn the very real power of standing up for what you believe in, even when everyone else is against you. You can't buy that.
I'm not a prude, what she does when she's 18 is up to her. But if I don't try to instill the appropriate values into her, who will?
God's blessings to you for doing your best. Most parents find it easy to control their ten year olds though, so I will say to you that the words you may soon be looking for are: "Oh my God, I can't believe she's doing........
You will find that you cannot control what your daughter watches on TV or the interent, and for many reasons. You cannot babysit them 24/7, they will be at their friends' homes and will watch TV, (not that the average "family" show isn't borderline pornographic anyway). They will go to the public library and have access to porn book, and yes, even porn internet sites.
The other major problem is that so many families don't have the luxury of having two parents anymore, and the ones that do don't typically have the luxury of stay-at-home mothers. No matter how much you may think you're 'protecting' your child from pornography just take a look around you and you'll see that it's on the side of your local Public Transportation busses, it's on billboards, it's in every window display at the malls, it's in Teen Magazines, it's in your family newspaper, it's even being TAUGHT in schools under the guise of "sex education". Oh, and you better add Major League Baseball to your banned TV list of programs, because your ten year old will learn all about Viagra and the dangers of four hour erections if she watches it.
Anyway, thanks for the "no" advice, and good luck as your daughter gets older. Keep up the good work.
