As others have pointed out, I'm happy for you that your mom is being looked after, but she is one of the lucky ones.
That having been said, the local dubs did look after my mom when she was on her last legs as well. My mom waited until she was old and sickly to become a dub, and it paid off for her. To her credit, she did not leave her property or money (of which she had little) to the WT.
When I was a dub, my elder husband forbade me to babysit for JW friends unless it was so that they could go out in service. I got yelled at for babysitting one child so a sister could take her other toddler to the dentist. I also got yelled at for babysitting my Bible study's kids.
