Has she had an ILS worker come to see her? (Depending on where you are from, they may refer to them as rehab workers or something else). They can teach her skills for how to shave her legs without cutting herself.

Another option is one of the hair plucking devices (not very pleasant) or depilatory cream.

It never hurts to take a little extra time. Perhaps another razor or shaving cream might help?

Is she using shaving cream? Is the razor dull?

Just takes practice. I'm on the last little bit of my sight, and I wet shave with a twist to open safety razor. I use my dominant hand to shave, and my off hand to feel where I need to shave, and to guide the razor

If you could afford it you could treat your mom to the occasional trip to the spa to get her legs waxed. It's not prohibitively expensive, it's no where near as painful as they make it out to be in the 40-year-old Virgin and it really is an effective way to get rid of leg hair.

All good ideas!! Thank you!
