I am retired and we have adopted our two granddaughters. I am receiving social security for myself and both my granddaughters. I don't understand why I am receiving their social security also and how I am supposed to use it. Am I supposed to give it to them, save it for them or use it to help raise them? My granddaughter thinks they should get it to spend or save however they want. She doesn't think we should use any of it for monthly expenses, etc. Your help would be appreciated.
