I will be in the same boat later this month--DH is going to Vegas with some friends of ours for a "guys' trip", and will be gone for 5 days. He's even going to miss a childbirth preparation class . . .
He's so darned excited about this trip, though (neither of us has ever been to Vegas, and he's never gone on a trip with "just the guys"), that I can't be bummed about it.
Well . . . not TOO bummed, anyway . . .
I like HappiLeigh's suggestions, though. I am going to stock up on my favorite foods, pick up some DVDs than DH wouldn't watch in a million years, and maybe invite a girlfriend or two over one night. Hopefully by the time he gets back, we will BOTH be refreshed and recharged for the "home stretch" before the birth!
