congratulations on the new baby. here are some suggestions; two baby blankets; one light and one warmer one; a warm baby hat; depending on the weather; light or heavy baby clothing and booties. for yourself; fresh change of personal underclothings, clothes and an ipod with relaxing music because you've just been through labor and might still be little rattled. best wishes to your family.
When I went to the hospital to have my kids (i have 3) I always brought there diaper bags, blankets, afew of there new outfits complete with little socks and hats. (They will take your baby's picture so bring which ever outfit you wish for that!) Bring the baby book to write in also. For myself I always packed a change of cloths for when I went home. While your in the hospital after you have your baby I found comfy pajamas are great. Loose fitting cloths are a must! Pads (the larger ones, more absorbency). And then brush, toothbrush etc.. And don't forget your camera to take pics!
