Im currently pregnant with my first, and am trying to get organised and buy some clothes before she comes home. My problem is i'm just not sure what sizes I should get and how many of each. I have some newborn and some 0-3 months, I feel like I should get some more newborn, but what if I have a big baby? How long with the newborn clothes fit her? I dont want to buy all newborn stuff just to have her grow out of them in 4 weeks time.
