My brother and SIL live in Delaware and we are all anxiously awaiting the arrival of their son (the first grandchild in the family). She is 39 weeks along and is scheduled for a C-section on Friday. But, my brother called this afternoon to let me know that they were in the hospital with contractions 4-5 minutes apart. Unfortunately, they sent her home and said to come back when the contractions get closer. What are the chances she'll have the baby before Friday?
