My must haves were my own quality super Maxy pads. You will bleed a lot and some hospitals give crappy pads. Snacks, for your stay after delivery, and make sure whatever pants you packed to wear home aren't just comfortable but are not tight in the crotch at all. Even yoga pants were to irritating down there for a bit.
If you get heartburn now take your heartburn stuff as I had it so bad through labour. And take plenty of water it's thirsty work :)
Around how many weeks were you all when u had your hospital bag ready
Most hospital rooms are very dry so be sure to have a good lotion or cream and definitely something for chapped lips!
I'd say make sure you have your phone charger and Earphones I ended up waiting a long time for my labour to be brought on had to have my waters broke etc without my phone I would have been terribly bored!
I gotta say with my first I had about 3 hospital bags. Didn't touch them.. besides my shower stuff before I left and my clothes. A lot of the stuff they tell you to pack isn't even on your mind after delivery.. phone charger, clothes, showering stuff and then baby's clothes. The hospital usually provides diapers etc. but the minimum is usually the best.
Bring nursing pads and the most comfortable bra you can find. I remember a ton of leaking with my first and even now with my second (I'm 40 weeks). Your breasts could swell at any moment after the baby is born so comfort up top is just as important as comfort below.
I found out when I had my first child that less is more. I didn't even use/wear half the stuff I brought.
Phone + phone charger
Money for snacks + food
A couple baby clothes (different outfits, anticipate possible blow outs)
A shirt or two
Maybe a Binky. I know it was a lifesaver for me.
You won't want to change out of your sweats. And they give you mesh underwear to keep your huge diaper pad in place.
Less is definitely more.
A boys bag is simple. An outfit change.
You're usually only there from 1 1/2 - 2 days. More if you have a c section or baby has complications.
And if that's the case, I'm sure hubby wouldn't mind running home for extra items.
