Great job packing early Fi!!! I think you've got plenty of clothes for both you and baby that's for sure! We only brought two clothing items for baby b/c our hospital provided diapers, hats, shirts and blankets while we were there! The time at the hospital went by so fast and your really just laying there in your nightie and baby in blanket the whole time!
Here are a few things that I packed....and some of these may be what you have already (I'm not sure what maternity towels are?)
- things to do while waiting to have baby - books, magazines, pregnancy journal, ipod, etc. this was especially important for DH (although there was a tv in the delivery room)
- snackies for DH (and for me for after - the hospital family room had good snacks but its nice to have the things exactly as you like them)
- tons of feminine pads - big huge heavy ones - the hospital also provided pads with built in cooling stuff - it was very nice for the vj after squeezing out another human being HE HE HE
I think that was it that I brought.....oh and we brought champange which the nurses said they let people sneak in for a little after birth celebration
