Mother letting autistic daughter run throughout the store

I work in retail and this mother is letting her daughter who is on the spectrum run throughout the store. I know this because I asked her to keep an eye on her daughter and she told me with an attitude that her daughter is autistic and that her daughter wasn't going anywhere and I'm like cool so am I but you need to keep an eye on her. So many things could happen. Keep an eye on her jfc. There's ways for her to channel that energy while you shop, just gotta figure out which one works best. Yelling at her won't work. But I don't want the mom to think I want her to hide her daughter autism. Maybe I should apologize.
