Thank you for the suggestion on contact and massage. Mom's left leg continues to bother her. The live in aid is massaging her foot and leg daily. It is helping.
I agree completely about touch... I try to spend some of my time with her every visit just sitting next to her holding her and consoling her. Since my dad is gone, he is not around to hold her throughout this journey.
I stayed with her over last weekend. Since I am such a deep sleeper (I have slept through many a storm (even a few earthquakes...) I got a great idea from a co-worker (thanks Ron...). I bought a wireless door bell ($25 bucks) and hung it on the wall of the second bedroom (uses 3 C batteries). The door bell package came with 2 small button units (for front and back door application). Mom can easily push the buttons. I put one button next to mom's bed and the other she carries in her robe pocket. If she needs me anytime through the night (if she is in bed or in the bathroom) I am just a pushbutton away. Of course, my mom had to push it about 10 times the first day just to test me
