I bought one or two new NB outfits (I had to have a cute going home outfit), and then a bunch of secondhand NB onesies. The secondhand ones are all $1 or less, so I figure it's worth risking $10 to not have to immediately shop if he's tiny. I believe the bag of 0-3 clothes a friend handed down to us has a few NB things, too, and I figure at least a couple people will buy tiny stuff for us. Now that they're predicting a small baby, I may buy a few more NB things instead of just assuming he'll be in 0-3 quickly, but I at least have enough to get through the worst of recovery before shopping if I need more. I'll bring a cute 0-3 sleeper to the hospital just in case he surprises us, too.
