Nah. My grandma gets paid because she watches my 1 year old cousin Monday-Thursday until she gets out of work. I watch him for a little bit, but my grandma is the one paying the bills, she deserves the money.
I also watch my 59 year old grandpa who got diagnosed with early onset Alzheimer's. He lives with us, and honestly it's the least I could do. My grandparents took custody of me and my brothers so we didn't have to go into foster care. He took care of me when I needed him, it's my turn to help take care of him, y'know?
