Is this stupid?

I know a family who works in healthcare. Their parents usually take care of their child when daycare isn't open. Due to covid-19 the daycare is now closed and they are working more than they usually do. Their parents are considered a risk group and shouldn't meet people. Would it be stupid to offer to take care of their child while they are working? I'm a stay-at-home mom with a six months old and a three years old, who has health conditions, but his doctors say he isn't technically in the risk group as his health issues doesn't have anything to do with lungs/breathing or his immune system. I'm trying to help out, but maybe it puts my own family in an unneccesary risk? What would you do?
