Stretch Marks ??

Jenny • Mama to my sweet daughter and expecting #2 in July!
My mother (bless her heart) gained many many stretch marks thanks to my sisters and I. I'm sure I'm not one of the lucky ones who will get away with none... but I'm still gonna try my best to decrease them! What do you recommend and WHY?? I'm browsing Amazon and in my cart currently are Bio-Oil, Palmers Cocoa Butter & Vitamin E. Any thoughts? I'm 5 weeks preggo by the way... just getting a head start!
