@iirockskiinies9, look on Pinterest or google it, there are tons of check off lists...also on YouTube you can see what a bunch of other ladies have packed.
For baby- socks, mittens, going home outfit, I packed a few extra onsies, pacifier if you use one, a bottle just incase, a few diapers/wipes if you stop somewhere on the way home, blanket, boppy pillow, car seat.
Mom- underwear (comfy and willing to be pitched), pads, deodorant, hair tie/head band, makeup, nursing bra, refreshing sweat wipes, soap, shampoo, robe, pjs, comfy clothes to go home in that would fit you when you were 7 months pregnant, slippers/socks, Chargers, glasses/contacts, toothbrush and toothpaste
There are good lists available on Pinterest and online and I went to the 99 cent travel aisle in Walmart and target and got my toiletries for the hospital because they have the mini travel ones which make it nice for packing!
