Evidently, they wasn't to young to know what they were doing when they were laying on their backs!
As parents, we should teach our children safety and let them know what is going on and what could happen. So many kids/teenagers are not educated in sex. They were mostly sheltered as kids. I watch teen moms and some of the parents go on there and blame themselves for not telling them about sex and protection.
Question is, at what age do you start talking to them about it? My daughter is 8, in a few years she will be reaching puberty. She has asked questions and i straight out told her without being to volgered<(i think thats what i'm trying to say) As she gets older, i'm sure more questions will come to mind as i will get in more detailed with her.
The economy is so bad now and we all want to do what is best for our kids, maybe that's why bringing another child in the world isn't the best option. Then again, there are woman/couples who can't have babies, then people should adopt, me, personally couldn't give my own up.
