Baby book for the footprints!
Tucks pads! If you tear or have an episiotomy they are great to fold and place between the stitches and pads/undies.
A robe and slippers/flip flops in case they make you walk the halls to speed up labor.
Extra panties and pants.
Bring grandma undies, and large pads. I was shocked with my first baby how heavy the post bleeding was. If youre going to breast feed and have a breast pump, bring that aswell just incase you have any feeding issues. I had to send for mine because my babe wasnt latching properly at first. Hair ties are important, chap stick is always nice too.
Camera, batteries, memory card, pjs, cloths for babys hospital pics, going home clothes, deo, shampoo, pads, slip on shoes, robe, makeup, and a pillow from home are just a few ideas..
I put portable DVD in ours!
clothes for you and baby, nappies, formula if you're not breastfeeding and the hospital doesn't provide it, pads, breast pads, nappy cream, bring your own pillow (last time i was soo uncomfortable on them hospital beds, this time i'm definately bringing my own pillow)... what else.. magazines to read? phone or a tablet with apps? if you will have a shower there, get your own towel, hairdryer, etc. toothbrush, put a good few pairs of underwear and pyjama bottoms, incase your water breaks before you go to the hospital, you'll leak water till you deliver, so it's good to have extra underwear and pyjamas, and after delivery you might leak blood out of the pad.
don't know what else :)
