Well for you just things you need like to shower and brush your teeth, makeup. I didn't use make up because my son took all my time lol. You'll need something comfortable to go home with like sweats and a shirt.
On your babies bag depends but most likely a long sleeve onesie and some pants a cover, burp cloths if your using them, and for you I don't know id they'll supply you with it but you'll need pads in the hospital I was in they gave me everything pads, ice packs, (if you tear) and get stitches that's for the pain, some girls have pain while urinating but I had none that's about it and maybe some money or a camera, charger, laptop if your hospital lets you some don't.
Your welcome I had my baby at 39 weeks, I only took my bag that day but when I got there I was on full labor at 10cm. I left like 3 hours before that because I was only 2cm was in labor for 7 hours with back labor but I did it natural because it was too late for an epidural, and they had to break my water...so yea.
