The rental house has a tub. I would prefer a walk-in shower but can't get one. She has me and my sister to help her when she needs it. I think that she needs a aide to help out with her care. My sister and I are both worn out. Mom is refusing to let me get some help.
I LOVE those no-rinse products and sometimes use them myself.
As careful as we are, non slip mats and safety bars, the risks are still there for falling.
Allow her to wash up with a pail of water and soap or the no rinse soap if you need to. My mom took a shower once a week but sometimes when she was too tired she did the sponge bath.
Get aides in to help. Explain they are there to help YOU & your sister.
That is exactly what my Doctor told me in a similar situation.
