After going through the birthing process with their first two children, Kris and Paul Demchuk figured they knew the drill pretty well.

The Snowden couple had gone through an 18-hour delivery with their first child, Kaylee, now 6; and a 12-hour delivery with their second child, Bubba, now 4. So they thought they were pretty safe in believing the birth of their third child would also be a long process. Besides, the baby wasn't due until the next day, and Kris had never delivered until after her due date.
