J.S.
Having multiple plans is a good idea. With our second, my water broke at home at 3am. A neighbor took me to the hospital while my husband stayed with our 3 yr old until 5am. A teacher at our daycare had offered to take our oldest to school with her (start time 6am). So, husband called her (apologizing for how early it was and dropped number #1 at her house). He then came to the hospital and I had #2 around 7:10am.
It's really good of you to be talking about this now. Don't be afraid to ask friends, neighbors, relatives to help out. I was really surprised that the daycare teacher offered to help - made things tremendously easier for us.
Good Luck!
