Re: Good news :-)
You also set the bed low so she can stand up without having to worry about falling. IF she is going to get up make it easy, not more difficult. If you have the hospital bed, lower it, not raise it. You know she is a "mover" so make it safe for her to get up, not more difficult. check with the nursing homes, or the hospital and ask them where they get them. Check with a hospital supply, or a school supply-it goes under the sheets...
good luck dear!
