I need someone to watch my elderly mom. Do I need to get a cna or will a neighbor lady be ok?

Depends. Lots of variables. What kind of issues does your mom have? How healthy is your neighbor? Is this just temporary? Or are you looking for a long-term solution? What if something is broken or missing from house - how will you feel if it was your neighbor? At least w/hired help, they should be bonded (insured). Plus they have more training. Discuss this w/other family members.
