First time around, thing I was really proud that we brought: a small bag for my husband (shaving kit, brush, deodorant, toothbrush/toothpaste, breath mints, quarters for snack machine), but more importantly: HE brought his swimsuit, on his own. He changed into his swimsuit so he could help me with my first shower after delivery. I was always very independent, and this was a real bonding time because he was so helpful and I really needed him. It was strange, but sweet.
2nd time around, I brought "our CD" (because we were oldschool and didn't have an ipod yet) with really good, relaxing, but happy songs, for recovery time and the 2 days after the baby was born. Every single nurse commented on that CD because the music is greatness, some asked for the playlist. This came in handy because my husband was busy with our oldest boy and I had spaces in time that could have been kinda lonely (baby sleeping, me alone, couldn't keep a 3 year old at the hospital all day).
