I just did my check list today:
Car seat, stroller, base, onsies (long sleeves and short sleeves) sleep sack, ,mittens, hats, socks, burp cloths, wash clothes, bibs, pacifiers, blankets, diapers, wipes. first aid kit for baby's (thermometer, medicine, nail clippers, ect.) Sold at babies r us, Burlington, and target. baby lotion and baby wash, for rashes you could use destin, olive oil, lavender oil and cocoanut oil. For the crib or bassinet have extra sheets, pee-pee pads. If its winter time for you a jacket and some sweaters. Bottles, bottle cleaner, nursing bra, nursing pads, nipple cream. Diaper bag with changing pad.
Hope this helps.
