I honestly don’t think little kids understand what people mean when they say “be careful”. When my kids were younger, I’d say something like “be careful the sidewalk is icy!” and they’d just run full speed and slip on the ice.
I think kids just think “be careful” is just something nice you say like “good luck”.
