Like some of the other mamas, I had these when my hips started growing about your daughter's age. Until I was in college and finally saw that other girls had them, too, I was extremely embarrassed of them. You're probably already normalizing it for her, but I hope she knows this is a normal thing that bodies do to compensate for growth spurts. And just a word of caution, and I mean no offense, but if you make a big deal of getting rid of her stretch marks, she may be even more self-conscious of them. I used all kinds of creams and vitamin E oil with no success. Time was the biggest way to help them get less noticable.
