Hey Rich....
Congratulations and Good Luck with the young'n.  Is this your first?  Honig's has those little ref shirts....
Your wife is a real sport....all the best to her....keep us posted!
My wife was 2 months past her due date with our first, 27 years ago....finally got tired of waiting anymore so we went to a Marquette/Wisconsin Badger BB game at the field house and jumped up and down with the band.  Worked like a charm.  Eric was born the next day!  
Best wishes to you and your family!
