I know that they pretty much fly through these sizes and stay at 2 for a while, but I'm trying to decide how many I'll actually need. At the moment, I only have one regular pack of newborn and I know I'll get one or two more. I'm debating on buying the size 1 in a case from Amazon. Or even newborn, if he might stay in them.

I have big babies, too, and I know it all varies between LOs, but I'm just trying to get an idea.
