Explaining a gap after caregiving or layoff - any advice?

I took time out to care for a family member after working as a bank teller. There are 7 people counting on me, so I am trying to be careful. I am nervous about being filtered out. What do you say in interviews?

Keep everything in writing and save the confirmation numbers. It saved me later.

A short, honest line such as 'family caregiving' is enough for most employers. They mostly want to know you are ready now.
