I think in one way it shows how hard it is as a teenage mom to have a child but then on the other hand some teenage girls would actually want these girls lives. After all they are famous because they are young and have children.
I cant speak for all shows about teen pregnancy but i watch teen mom and there is absolutely nothing glamorous about it. I feel more disgust and or pity for some of these girls than anything else. They all struggle immensely and none of them find true happiness after becoming young moms. I let my girls watch it.
