I have really been dreading this too as I am already so tiny to begin with. The book that I have "What to Expect when your expecting" says that you may be able to minimize, if not prevent stretch marks by keeping weight gain steady, gradual, and moderate. The faster skin stretches, the more likely it is to leave marks. It also says that promoting elasticity in your skin by nourishing it with a good diet (especially vit c foods). Personally I don't think it could hurt to use the vitimin e lotion or oil to help. All these things combined may just b good enough to work
