Join The Toy Society. Make and drop a toy.
We tried to do this as a post-bedtime date. It did not go well. The munchkin wasn't settled in bed until 9:00, and the tiny one refused to sleep. So I ended up coaching the hubby through most of the toy making while jiggling the baby. Needless to say, I wasn't much practical help.
We got about halfway to accomplishing this and a quarter of the way to accomplishing this before our two hours were up and we abandoned both projects and went to bed. Better luck next time.
