Just in case.......
Try to prep in case YOU get sick and still need to care for the children. Make some meals ahead and freeze it, have a big jug of water near your bed or resting area, tissues, wash bowl and needed meds. You could wake up unable to move, sick with fever and so on. Teach them when to call 911.
Teach the kids how to heat and get their own meals if needed, do a load of wash, load the dishwasher and care for you and each other, feed the pet, if you get sick.
