Will your kids shift to sleeping in during the summer? I have 2 that will sleep in and the other would be happy to play video games or watch a movie to stay quiet. You could have a list that needed to be completed before screens so they were ready for the day when you finished. Is that a possibility so you could work in the morning? And then maybe put in another hour or so in the afternoon, giving you the opportunity to reach your bosses more easily.

I like the idea of planning a few day camps to break up your weeks if it's a possibility.
