Pregnancy and the Prefrontal Cortex

Today I've decided to be brutally honest. In the last few weeks I have been brutally honest with myself ABOUT myself, and let me tell you, it is FREEING!
First let me tell you what I've learned about this part of the brain called the prefrontal cortex. It's the last part of the brain that develops during adolescence, usually reaching maturity around a person's mid 20's. (earlier in women, later in men, since we all know men develop emotionally slower then women) Anyway, the way I understand it, the prefrontal cortex is like the "adult" part of the brain. It is able to weigh pros and cons and not make impulsive decisions. It helps us to lose that egocentric, thrill seeking behavior so often seen in teenagers. It also enables us to have meaningful relationships- with more attention paid to the need of our partner rather then our own. Now, this is actually relative to my first point.
Teenage Pregnancy. Is it possible that teens get pregnant at such an alarming rate because of that part of their mind that seeks instant gratification, a thrill,
and doesn't think through consequences? That was a rhetorical question. So perhaps, it would be wise for parents to be pro active in their child's family planning? I understand that a lot of people believe in abstinence (I myself am a strong believer, if you can imagine that!) however, in addition to parents sharing their own personal convictions, how about opening the lines of communication about safe sex and birth control? I think parents taking an active role in their child's birth control method (whether it be abstinence or the pill) is crucial.
(ps- girls shouldn't be the only ones in charge of birth control. Boys, don't want a baby? Learn to wrap it up)
Teens are not meant to be parents. Case in point: Ever seen Teen Mom. Bravo, MTV, another quality television program. I'm not saying teens can't be good parents, but their brain chemistry isn't really up to a parenting standard. I will cite myself as an example. I was irresponsible with birth control. Along comes Korinne. I wasn't ready to be a mother. I loved Korinne, but to be honest, for a long time I felt like I was babysitting. I wasn't a harmful mother, but I needed a lot of help and guidance, and I thought more about myself then I did about Korinne. Now, I wouldn't give her up for the world, but had I waited a few years I think I could have been a much better mom. For a long time I was ashamed about my emotions surrounding Korinne's birth and early life, but I can recognize now that I did my best, and I can proudly say that through the last 3 1/2 years I have become a parent I can be proud of. More importantly though, I have come to understand WHY children shouldn't be having children, and that, as adults, we need to look at what WE can do to help prevent teen pregnancy.
I did have another point- but I have to do a part II tomorrow.
