That's a good idea too! Had a slight change of plans. Instead of styrofoam cups for her coffee, I just went to Goodwill and picked up a couple of those dainty little tea/coffee cups that are really light weight. Got a plastic cup with a lid that's really light to that I figure she can use for water or Pepsi, whatever.Sounds like you have thought this through. I use a baby monitor to listen if my Dad needs me. I can't communicate back with him through it but he doesn't have to find the monitor and key it up either. He's a 100 yrs old and legally blind, this works best for us.
