I am so sorry to hear. I can understand some of what you are saying because my grandmother was sick and passed away last year. She got sick at Easter time and we thought she was not going to survive. I had explained it all to my DCfamilies and the possibility that i have to close daycare suddenly and required immediate pick up if we got the 'dreaded call'. They were all very understanding, and i didn't worry too much about it because I knew they all had solid back ups and i have good DCfamilies. My grandma got better, then took a turn for the worse, and passed away May 23 of last yr. I took 2 or 3 days off the first time she was sick, and 3 days off when she passed away and not one single parent gave me a hard time. One actually told me to take more time off

I would not worry about taking the time off that you need too. You have to come first in this scenario so you can be with your father and your family. You will not get this time back so spend as much time as you need to with him.
