I've made some changes in my home life in the last week or so. My 2 year old is now staying with me full time. I wrote with him at home last week, and I thought things went ok. In another couple of weeks, my 5 year old gets out of school and is home for the summer, too.
I think I'm going to switch to more "quick hit" pieces and write chunks as I go. Thing will likely be smaller and more bite sized, but I should be able to keep posting something each day.
This is all in progress and an experiment. I'll see how things go and how things feel. My son may also be getting the hang of playing by himself for hours each day, so we'll just have to see.
