Having raised 5 children....3 girls & 2 boys.....with 11 grandchildren....and 2 great grandchildren.....it is imperative to establish early on the real core values, virtues and some religion what is wrong or right in their upbringing. However, once they become teen agers...and heavily dependent upon the company they keep (their friends)...they form their own views, opinions and desires. No matter how hard we try to influence their thinking, their needs (right wrong or indifferent) form their standards.
The influences they are exposed to daily...school...television...the movies...some friends...THE INTERNET...have been influencing them long before they ever heard of Sarah Palin.
All one can do as a parent is the best possible in the loose morals society/environment we they live in today.
I know....our first great grand child was concieved and born out of wed lock. Our grand daughter (the mother) a perfect model of what every parent would like a daughter to be.
They (mother and father) both finished high school. They are now married...both going to college.
As much as I/we were upset and shocked.....it happens in the best of families.
Until such time as core values are returned to that which they are exposed to and bombareded with every day...it will continue to happen...including in the best of families.

Palin's daughter is yesterday's news to most people already. The other influences mentioned are on ongoing and continuous. Want a good (or bad example)? Some schools offering condoms to assure safe sex.

I say good luck to those raising kids today. The prognosis...it can only become more common place...unfortunately!!!!
