I've actually only ever watched one episode of "16 and Pregnant".
I will say that after watching one episode, it really gave me insight to these girls lives. It by no means glamorized them...at all. I was 19 when became pregnant with my daughter. That is still very young. However, it turns out that there has been a decline in teen pregnancy over the years, and some think that 16 and Pregnant is to blame. Check out the video below. It links to Upworthy where they report this statistic.
