We know a Mexican family (probably parents are illegal) where the daughter was pregnant at 15. I went to the little boy's first birthday party and the then 16 year old mom was going to get their pictures done beforehand and wearing an extremely revealing dress. I was really shocked at the dress and felt a little embarrassed. Well one of her younger sisters used to play with my oldest son even though she was a couple of years older. Well we hadn't seen her for awhile one time, and I couldn't believe how she had changed from a 9/10 year old little girl to a developing way too rapidly 11 year old. Now she can't do anything about her very fast developing breasts, but her parents could do something about the way she was revealing them. It was a shock. Unfortunately, I see her going the way of her sister--pregnant at 15 if not before. The oldest sister is now 17 and expecting #2.
I can imagine that girls want to emulate their role models.
