After Aiden urped on me twice on both Tuesday and Wednesday, I decided that babysitting has some hazardous duties such as burping when the kid has a cold. I now carry an extra T-shirt to my "job" as grandparent babysitter. These things aren't in the manual. "Be prepared" has become my motto (with due respect to the Boy Scouts who established the phrase a few years ago). I still enjoy the work.
