Worth it to try to prevent stretch marks? Any success with cocoa butter?

[Anonymous]

I used the stuff in the white pump bottle for stretch marks (Palmers Cocoa Butter -- the popular one they sell at Target and CVS) from the time I was 7 weeks pregnant and managed to avoid them. I was certain I was going to get them because everyone else in my family has, so I'm not sure the genetics thing is entirely what it's based on. But I also didn't gain that much weight (27 lbs) so that might have helped as well.
