Sorry if this is a silly question, but I'm new to all this! I'm expecting my first baby due 28 Feb 2018 (aaaah!) and my mum excitedly bought a lovely little snowsuit from M&S. it's size 0-3 months but it looks huge! I'm wondering if my newborn will fit it, or if by the time it does, a snowsuit will be the wrong thing. I'm totally clueless when it comes to how to dress my newborn and wondering if I should exchange the snowsuit for something else at M&S a sit wasn't cheap at £22.
