Mom, 98, fell and fractured dominant arm - in a sling. She was discharged this weekend and I am finding it so hard to get her in and out of bed to commode. She is overweight and has limited mobility. Until I get more aide hours, it's just my hubby and I trying to get her to a commode by her bed. I cannot do it alone. I ask her to urinate in her diaper and she says she's trying but cannot. Is there something I can do to get her to "let go"?
