My justification

Several family members have asked me about the over/under being 9 pounds.

I chose 9 pounds for several reasons:

1. That is BIG.
2. Jennifer is scheduled to have a c-section 7-9 days prior to her original due date (there is a 2-day discrepancy).
3. Babies gain about an ounce a day during that last week or so.

Jennifer indicated that the wager should be over/under 9.5 pounds (9 pounds and 8 ounces). If you subtract an ounce per day, then you are around 9 pounds!

If you don't like that wager, then how about when Connor X Thompson will be born (Jennifer is scheduled for a c-section on December 16, 2009).
