Do a puzzle together.
Because the munchkin is 2 years old, we decided to do this date at home after his bedtime. I'll admit, it took us more like four and a half hours. It should be noted that our puzzle was 500 pieces, our baby required jiggling most of the night, and we took a break for root-beer floats at midnight, so your results may vary.
Score of 9 on the 'novel' scale. Score of 2 for 'exciting.' But it was a pretty good time, as evidenced by the fact that we stayed up until after 1:00 am completing our puzzle. And we let the munchkin put in the last piece at breakfast.
