Glad you figured out what would work best for you and your family.
We had my FIL on stand-by down the street when the time came close, but thankfully my water broke at 330am and I gave birth at 525am, and the kids slept through ALL of it!! My 3rd child actually did come out about 5 mins after the birth when she heard the baby crying. Then my second was up about 20 minutes after that and wanted to watch the midwive do the baby's check after a while. My first didn't wake up til 3 hours later!!
