Use all 24 hours of the day and all seven days of the week to best effect. Some work will be time specific and some won’t. If you have to keep to appointment and meeting times, move the other things you need to do in a day around. Basically design it from scratch as if you have no knowledge of day/night, sleep/awake, weekday/weekend, or set eating times. If you get time to relax at 5am on a Tuesday, take it. If you get time to work at 1am on a Sunday, take it. If you can work and be mobile, do it (eg working on your phone in the park or laptop on the floor next to the train tracks). If you need to have a big meal at 10.30am and toast for dinner, do that. If you don’t have time to cook, put all the food groups on a plate, lay a blanket on the floor, call it a picnic. If you have people who can support you remotely, take them up on that (eg prop auntie or grandad up on a video chat in the corner and let them read a story/be shown every element of the game)
If you can work two and a half hours a day whenever they are asleep, one hour a day somehow mobile, half an hour a day with a video chat, and use two half hour TV programmes a day you’ve got 35 hours covered over the week. Of course no one can flex to that extent to use them all but it hopefully gives ideas.
When they are awake, you can do the schooling needed. The problem comes of course when they are expected in online groups or lessons at specific times and you are expected in meetings or to do specific hours, we had a lot of that over the last lockdown. Some of my DC were expected to upload progress hourly and some had mountains of stuff to get through and too young to self manage.
The whole thing is shit and I’m off to open the whisky just thinking about doing it again
