this is my fourth go round but i remember the first time we forgot to bring a baby blanket and ended up taking the hospitals and we only bought one baby outfit and it swallowed will up! poor guy.
id say a must have would be hand sanitizer to hand out to guests before they hold my baby, some lip balm , a list of people to call, a calling card, change for the machines......
i never have bought my own night clothes, mainly because i dont have any.... i either sleep in sweats or tshirt or nothing at all, and i refuse to buy night clothes just for the hospital and then they get ruined.
oh yeah, i always pack a good writing pen, there is a lot of paper work to fill out after u have a baby.
