Do they have some sort of community where they live? Neighbors, faith, cultural? When I had heart surgery, we had three meal trains to feed my family while I was healing.
If so, make sure that you provide suggestions to these groups for what to bring. I still remember one mom who sent an amazing over-the-top meal that I would love to eat today but could not then and kids refused, so I had to give it away.
You are a good daughter. Wishing your mom the best!
