I understand. I'm not being critical of you -- just trying to help with what's worked for me in a similar situation. I mostly did squats and push ups, and the extent of my son's involvement was to add a little bit of . . . resistance . . . to the latter exercise. ;)

I understand the difficulty; when you're a sole caretaker, focused time to do things tends to be limited to naps and schooldays, and then it tends to be used for more system-critical things like taking showers. I hope your situation improves in time. :)
