I have nursing bras, comfy pjs for after delivery, toiletries
Going home outfit for baby, boppy pillow, blankets cause it’ll be cold
And comfy clothes for daddy, and money for the vending machines
It depends on what your hospital provides you with
I packed mine after our hospital tour

For you: Chapstick, lotion, cell phone charger, extension cable, comfortable clothes for you to be in while at the hospital and for the way home, tooth brush, tooth paste, hair brush, extra hair ties, deodorant, shampoo, conditioner, body wash, towel (just incase you want to take a shower),nursing bra and nipple cream if you are planning on breastfeeding, snacks, your own pillow and blanket (this was my personal preference)
For baby: pacifier(if you are going to use one) going home outfit, outfit for the hospital(I personally recommend the gowns that they sleep in for while in the hospital, makes changing diapers alot easier), small blanket, socks. The hospital should provide you with the rest.
You will need more stuff for yourself than the baby. Also bring an extra bag with because the hospital will probably give you a lot of stuff to take home.

A new wardrobe. Your own shower stuff. Baby clothes. Chargers for your gadgets. Money. Pillows and blankets. Activities to do, puzzles, coloring pages, card games.
