Winter clothes are all on sale now, but I have no idea how to buy for next winter! LO is only 17 weeks, and below the 2nd percentile (yes, 2nd! He was a preemie). So I have no idea how big he'll actually be next winter. I have bought a few things for this summer/fall, but I also don't know how big he'll be, and don't want to waste money on things he won't end up wearing. Oh the dilemma!
What does everyone else do?
