The minimum items that you should have on hand for your baby when it comes to clothing are 7 onesies or bodysuits, 2 hats, 2-3 swaddling blankets, 4 baby gowns or sleepers, 3-5 outfits (either one-piece rompers or tops and bottoms), and 5 pairs of socks. Keep in mind that the bare minimum will require you to wash the items more frequently.
