Update by Emily:
Lily and Austin came over to the hospital, but bedtime came before Grayson, so they went home. I guess they will see the baby in the morning. It will be fun to wake up to a new baby brother. Amy is now dilated to a 10 and on oxygen to help the baby's heart rate. They say she'll be able to start pushing in about a half hour.
Here is Amy as they are breaking her water:
