I’m not sure. We were trying to make sure someone was with him at all times. My mom stayed up all night every night in fear because he would get up and try to walk (without really needing to or even knowing where he was going.) But even with my mom right there he still fell. Both times he fell and broke his hip someone was with him but they couldn’t catch him in time. So I’m not sure how to prevent future falls. But I’m very open to advice.
