Stretch Marks are down to skin type hun, some peoples skin isn't as elastic and can't cope with the sudden growth - the only way to minimise them is to not grow too fast (i'm not sure exactly how you're supposed to do that, and i failed miserably with both my pregnancies) If you get them you'll learn to love them as a sign of the beautiful baby you grew inside you, if you don't then you feel lucky that they passed you by and you came out unmarked- neither is a bad thing. xx
