Clara’s visibility?

Our daughter has dwarfism, she is six years old but 1‘5“ tall and 18 pounds. I try and let my daughter be as independent as she can, of course when it’s not safe when we are out in public she will either be in a stroller or carrier. But when she is walking around, especially in public. People aren't expecting a toddler sized six year old at times. I want to let her walk around when she has the energy for it, but a lot of people are in a hurry or just not paying attention and have bumped into her, which at Clara's size means that she gets trampled over, or they will just step over without realizing (This has only ever happened a few times but it still happens$
Is there something she could have/where/hold to be more noticeable? We have tried clothing items but still that didn't do anything. It's almost like whatever we do it needs to be more in the line of sight for grown-ups if that makes sense


Also just to clarify I did make another post about this but I wanted to make a specific one focusing more on this.
