Yeah the BBH all in ones are what I want to use eventually, but I saw the one size fits all ones and they just seem so bulky on the newborn setting so I thought i'd go sized so they are a bit trimmer.
Janine1511 that sounds like a good idea, smalls would probably get you through until bub was big enough to fit in one size fits all comfortably. My DS is almost 4 months and the one size seems to fit him quiet comfortably now

If not smalls use the flats with small covers, i found they fit really well.
