aside from newborns, you should always get the big box you go through them way faster than you think. My LO wasn't in newborns but for maybe a couple of weeks then we moved on to 1's. I tired giving them away and then decided to keep any of the ones opened for when I have another child. If you are wanting to stalk up i'd start from size 1 or 2 and go up from there.
