Hi girls Wanted your opinion on moisturisers/oils. I am only 6 weeks and already my @@s are more than a cup size bigger, so I'm wanting to do all I can to combat the dreaded stretch marks. Do any of you have any advice? I know "Bio-oil" is meant to be good, but as it's super expensive I wanted to see if there were any alternatives out there. Also Boots have 3 for 2 on all skinare at the mo, but would I really need 3bottles of the stuff?
