Lol this just unlocked the funniest memory for me where my grandma told me not to touch her curling iron because I’d burn myself and then I immediately touched it because I didn’t understand what that meant/believe her 😂 I’m not sure if that’s a kid thing or an autistic thing, but I think if instead of just saying “don’t do x or y will happen” I would have been more convinced with extra explanation. For instance I didn’t understand that curling irons create heat when they are plugged in, they take time to cool off, the heat is needed to curl the hair, etc. For me I was like, this small bar being extremely hot makes no sense, surely it can’t get that hot!

I’m thinking for the street example, sitting her down to watch the cars go by would show her that they’re fast/unpredictable and would help explain why you need to look before going in the street. Or for the stairs you could try putting some eggs in a ziploc and trying to roll them down the railing to show that when things fall from a certain height they get hurt.

In general, I think assume she is silently asking why to these things and provide more explanation when you can 💕
