Protecting my babies

I read this statistic in the September 2009 issue of Parents Magazine:

For every hour of adult content that kids ages 6-8 watched over a
two-day period, their chances of having sex as young adolescents increased by 33 percent.

This study came from the Center on Media and Child Health at Children's Hospital Boston. I would like to read the full study.

These are my babies. I worry constantly about giving them a leg up in this promiscuous society. I want them to be happy and have good marriages. I think I will continue along the current path of being extremely protective of what they watch. Some people believe that they have to be exposed to it to be able to deal with it. I agree. It's just that I think the older they are when they are exposed, the better. I want my children to be sensitive, not desensitized.

What do you think?
