This is my first baby and I have no idea what to pack to go to the hospital when the time is right. I am only 31 weeks but I like to be prepared. You never know what will happen.
Clothes for you AND baby, blankets, house shoes (for comfort...) plenty of underwear for you (bc like you said, never know what will happen.) Maybe a bottle for the baby (if you are bottle feeding) breast pads (so you don't soak your gown and bra...) and stuff like that. Also, bath stuff, in case you have to stay more than one night.
Some comfy clothes for you
A couple baby clothes
Clothes for me, clothes for baby, tooth brush, tooth paste, hair brush, body wash, shampoo, night gown, CAMERA, baby book (for her feet and hand prints), books that I read to her throughout my pregnancy, music that I always play for her, quarters for snack machine, and clothes for father.
This is what i packed-bathroom essentials(toothbrush,razor,shampoo etc) underwear, pads, socks, camera, laptop, slippers, robe, towel(hospital towels are thin), going home outfit, i brought 3 sets of pjs(old ones in case thet get ruined), snacks for SO, a bag of coins for SO for the snack machines. For the baby- 5 pj outfits, a few diapers, going home outfit, recieving blanket, wipes, passy, socks, hat.
I didn't take much, mostly because my hospital provided nearly everything. I took:
Clothes for baby and me to wear
Going home outfit for me and baby
Phone and charger
Shampoo/conditioner and body wash
Slippers and socks
Thats about it. I didn't even take more than a pair of underwear to go home in, my hospital provided mesh throw away ones that were great.
