B.S.
I have never seen Secret Life/American Teenage or Make it or Break it....so I have no idea what those are about.
But as for 16 and Pregnant and Teen Mom, when my girls are old enough, I could see letting them watch these. I think the importance that comes from these shows are A) Almost every girl pregnant on the show is a result of not using protection B) You may think you've found true love in high school but in most cases that is not the case and C) Its not easy raising a child especially at a young age. So yes, I do find value from these two shows. (EDIT TO ADD) I don't expect these shows to be the way they will learn about sex and how to prevent pregnancy. But, I think the show does a pretty good job not glamorizing being pregnant.
