My mom is a person who suffers with having chronic UTI. She just got over one last week and I think she has another one now. What can I do I make sure she wipes right because I wipe her myself when she is at home. I worry about her having these UTI's so regularly, she is 93 and has Alzheimer's/dementia. Her doctor recommended a one time antibiotic for her which works for her but now she is acting the same way again. Any advice?
