So I guess you will deliver at NWH. I don't think you will regret it. I did a childbirth class there too.
Funny for us, but when we checked into deliver they apparently had been really busy and then we got in it was calm.
While in early labor I was walking the halls and noticing all these empty rooms, nearly 3/4 of them. So post partum we had nurses hanging in our room answering any and all questions. I would say 'hey, i don't want to take all of your time' and several nurses said no one was on the floor- just a fluke. Hopefully the same for you!
As for AWBW, I never had any issue with booking appts or talking to nurses via telephone...they seem pretty quick to respond.
