Oh I forgot to add this...

Dad bought a Door Bell system today. he installed one button in the Bathroom & put the other one on her side table. The bell (or whatever it's called) is in his bedroom, so if she ever needs him, she can Buzz him.

The next step will be betting a buzzer as a necklace. he said she doesn't need that yet, but he'll get a 3rd button & will turn it into a necklace when her legs get weaker. Right now she can walk just fine with her walker.
