Steve tell the lovely wife that in order to hit my guess she should be having contractions by now. You know, there is never a bad time to take up jogging
Is she nesting? My wife nested like crazy the day before the contractions began. Watch for the sign.
Since this is your first, here is a tip. Don't make the same mistake I did and pack only one pair of underware for her. Seemed logical to me......... after all, one day one pair! My daughter is about to turn 13 and my wife still brings the 'one pair' episode up from time to time.
Good luck in the feminine hygiene isle when the wife sends you for the inevitable need after the blessed event. My wife said 'pads' and through the keys at me. When I arrived at the store there was a fifty by eight foot wall of pads. I almost had a break down. Ever see 'Moscoe on the Hudson' with Robin Williams when he is in the store to by coffee and he goes into overload. That was me.
For those first sleepless nights there seems to be some magic in a clothing dryer, a load of wet towels, car seat and duct tape. Worked for me. Daughter on dryer, father on laundry table in the morning.
