How do you handle days when you are ill and cannot teach?

Audiobooks and documentaries as an independent learning day. After a year, children manage it without complaint.

Pre-built work packets for emergencies. Six to ten packets in a drawer, each with three hours of independent work.

Co-op friends on rotation. Two families cover for us on hard days and we cover for them.

Assign the older child as teacher for the day. The teaching consolidates their own knowledge and gives you rest.
