The best way to handle your Mom is to address her concerns. Think of how she is feeling. She must be pretty panicked to be calling her family. My Mom is 61 and had Dementia for 4 yrs. She can't even pick up a phone let alone talk. She lost all forms of communication. She can't walk, talk feed herself, go to the bathroom or anything. You are lucky you can still talk to your Mom. I would be thrilled if my Mom called me at 2:00 am to talk. I take care of my mom and only live 7 miles away,but it feels like she is very far away and will never come back.There is one thing that my Mom does that brightens my day, She SMILES! So have patients with her and be thankful its not you.
