This maybe long....I have heard that hospital bag necessities differ here in the US than the Uk. THat being said I'd rather be safe than sorry so I may have over done it, but my hospital bag is almost done! Baby's hospital bag isn't done yet but will be after I get a lot of the things I need after the shower. Here in the US, most hospitals will supply baby's diapers while there, pads for bleeding, and nursing pads. I will be wearing their hospital gown to give birth in but I have brought pajamas and a cheap nursing nightgown for after baby is born. I also packed a lot of panties that I don't mind bleeding in in case I bleed a lot. Then I have a going home outfit which is just a black sweatsuit and a t-shirt. Don't forget socks probably 2 or 3 pair and one to go home in. I've packed 2 sleep bras in case I want a touch of support while I labor and one for after the birth when my breasts begin to get sore filling up but I'll have surely have visitors and I want to be sure I have some sort of bra on. Also a nursing bra for the way home. I have packed a few nursing pads and a few huge pads. We don't have 'maternity pads' here that I know of so I just bought the thickest, heaviest pads they sell here and I packed a few of them for the way home. Like I said the hospital will supply them and they even supply weird little mesh underwear for the post partum bleeding. I packed about 5 pair of my own panties though incase I don't like the meshy ones and don't want to wear them home. I packed 1 pair heavy socks also. I put flip flops in in case the shower floor looks dirty as I heard that a lot from a lot of women. And last but not least I packed a ton of toiletries such as shampoo, face wash, toothpaste, toothbrush, lotion, contacts and solution, hair ties, brush, chapstick, etc etc. The list goes on! Like I said for baby most US hospitals will supply everything baby needs but a going home outfit, coat and carseat. I have even heard that the hospital I am going to used to offer carseats! Even so, I will have her coat, carseat, a few outfits, a hat, and the normal diaper bag necessities-Diapers, sensitive wipes, burp clothes, etc. I think our hospital will keep us for 24 hrs but I think it all depends on the individual situation. And don't forget your pillow, your phone, camera. Otherwise we live literally 8 minutes from the hospital so DH will be able to come home and grab whatever we need! Like I said, I'd rather have it done and be ready then go into labor early and have to dictate to dh what to bring me as he's a man and he won't do it right...or won't listen to me.
