I'm 21 years old and this is my first baby. I believed while heartidly that if I used cocoa butter and bio oil on my belly all the time I would not get any stretch marks. Let me tell all you Mommas out there... If it's in your genes to get them... You're going to. No matter what you do. It's taken a huge toll on my self confidence which is why I'm throwing this topic out there for thought. Don't assume you're immune and if you turn into a little mommy tiger, wear your stripes PROUDLY.
