I was shocked to notice this week that my 9yo dd is developing a few stretch marks at the top of her thighs though she doesn't seem to have seen them herself, thank goodness. She is growing like a weed but even so, should a 9yo really be getting stretch marks?? I know there's nothing that really stops them in pg but I wonder if there's anything to be done for children. Has anyone else's child had this problem and what did you do?
