Ok my DD is fast approaching her teens,
so what i have found works for us is
she has a computer in her room but no internet access, she can go on the net on our laptop in the kitchen where it is monitored. My friend was saying to me how her daughter was on the net and put in games and puzzles and a naked woman popped up on the screen...
we listen to cd's in the car not the radio or edited versions of popular songs

My daughter dances and has done since she was 2 , she loves wearing costumes and the make up but that is for dancing only. At home its age appropriate clothing which can still be trendy, no butt hanging out the back of her pants.
She has barbies and bratz dolls and has grown out of them now . She likes to look nice and dress nice.
We have discussions alot about behaviour, what certain things mean and why. because as much as you try and sheild your children they hear it at school etc. So education plays a major part. Alot of her friends already have their periods and have developed breasts and pubic hair, This is scary these girls are only 9 and 10.
But i really like to focus on her intelegience and inner beauty, i think it is really important for a young person to know they are worthy and loved.
