For quite a few years now I have worked from home and flexibly arond the DC. Sickness, holidays etc have rare impacted upon us.
Today, however, I had an important (to me) meeting and DD is ill. She can't go to school.
DH is in NY. Mother is hundreds of miles away and doesn't drive anyway. Friends would happily call in but I can't ask them to spend six hours with DD (it would take this amount of time to get there, have the meeting and get back)...
It has really made me think about how most families cope.
