For those of you in the UK when you say vests, I'm not sure what you mean. Please explain.
They are talking about onesies.
Those in the us... We seem to stay in the hospital a lot longer but our hospitals supply more things. Mine provided all the diapers I could possibly use, wipes, pads, mesh undies, peribottle, clothes and blankets for baby during hospital stay, thermometer, nose sucker, breast pump, etc. So I needed less baby clothes than most in the uk take. I only took one coming home outfit and it was enough. I brought a few burp pads which came in handy the day we were going home and fed a bottle vs. Syringe of colostrum)
My hospital gave me a bag of stuff like shampoo, lotion, chapstick, etc. They had plenty of blankets and pillows for me and dh. They had pre made formula there we could use.
So I am bringing pjs or comfy pants and Tshirts for after delivery.
Phone, camera, chargers
Food And drinks for during labor for dh so he doesn't have to leave the room
Present for big sis
Wipes for me ( loved these with first labor as I was having a clean out during induction)
Minimal makeup
Brush and ponytail holders
Glasses, contacts supplies, deodorant
Baby book
Bras for during labor and after
Socks, slippers
Flip flops for wearing home ( being induced made my feet swell way up)
Toothbrush and paste
For dh- tshirt and socks, deoderant, pajama pants for staying overnight, contacts stuff, glasses
For baby - going home sleeper and 1 onesie, a few burp rags, fingernail clipper
Carseat and baby blanket leaving in the car til ready to go home
