I have no idea why I am awake at 3:45am.....well, maybe I do.
If you look at your work calendar and you notice that most major stuff is going to happen during one week, that is probably the week that your child is going to get sick. That is now happening for me. Our server is down for an upgrade, an important document is due by Thursday and training is not quite ready. Cue the fever.
It's OK. Things are going to get done, but that means that you work on things in the middle of the night in-between bouts of fever and crying. It means you write long, detailed emails to staff members with to-do lists of things that have to get done. You start projecting how you will get things done once you finally make it back to work.
That's why I am awake. I am home since I am the only person my child wants when he is sick, but work deadlines wait for no one.
