When Im shopping baby clothes, I don't know what size should I really get.. I have new baby, first size, 0-3, up to 1 month Just wondering what should I really buy? Is it pointless to buy many first size clothes? I think I mostly have 0-3 months ones. Just been on Next website and there was new baby and up to 1 month available on one thing, so do I take up to 1 month? whats the difference?
