Stretch mark prevention?

shootingstars00

I managed to have no stretch marks with # 1 but I have heard over and over that you get them with # 2. I know they say genetics and all but I still want to try! I am thinking about getting earth mama stretch oil. The description makes it sound good as far as stretch mark prevention and also helps with the belly itch I got last time. Anyone tried it? I am also wondering about the smell because I have a sensitive nose. Thanks!
