My mother-in-law, who has moderate dementia, loves lotion. We've had to remove it, as well as liquid soaps and mouthwash from her bathroom because she rubbed them onto her face, into her eyes, and into her mouth. I put clear water into an empty mouthwash bottle so she could enjoy the motions of using a lotion. But her face and hands get dry, and she would enjoy using it on her own.
I recently removed the toothpaste after I entered her room to find it rubbed all over her face. I used a warm washcloth to gently wash her eyes, hoping none had gotten into them!
I hate removing these little luxuries from her, but must do so for her safety.
