My name is Amanda and I am a LPN who has recently taken on the care of my grandmother who has dementia and urinary incontinence. I am wondering about tub bathing and whether it would be a better option for her. We have acquired a wonderful walk in tub but have received some resistance when it comes to the installment of said tub from my grandfather. How might I convince him that it is truly necessary to the management of her daily needs? HELP!
