Does your daughter's neighbour look after her children, ana? If so, she works. She may not be paid to look after her own children, unlike if someone else did it and got paid for having a "proper job", but if she looks after them, is their "child-minder", she works. Wish people would get their heads round that idea.
If being a child-minder/carer for other people's children is a job, then it's a job when you do it for your own, pay or no pay.
Getting money for doing something is not the definition of work, even though most people seem to think it is.
