I packed for my delivery several outfits because I don't know how big he is going to be so I packed one pair of premie pjs 3 newborn outfits incase he got sick on any of his outfits and one pair of 0-3 pjs. A blanket hia grooming kit and then one set of travel size hygiene products. Oh and a burp rag.
Clothes, extra blanket, hat, mittens, socks, depending on if your doing this for the hospital you probably won't need diapers and wipes because hospitals give them to you after you have the baby and ready to use bottles if you plan to formula feed
Clothes, hats, burp cloths, pacifier (if you plan to use one), mittens, socks, booties, blankets, that's some stuff I packed. I'm also bringing his baby book.
