I did with Charlie and I didn't get any stretch marks. But I didn't this time around and so far so good. My mom didn't get stretch marks so I think she just passed those genes down to me.
My friend told me his wife used cream religiously for her first pregnancy and didn't get any stretch marks, but then didn't use it at all for her second pregnancy and got really bad stretch marks.
Did anyone use stretch mark cream and have it work/not work for them?
