Actually for a child that young, not possible to teach it anything and it won't just touch the fire and back ofd it'll grab it and get burnt and scarred before it backs off and even then it'll just do it again because it's not possible for it to learn at such a young age

I really hope you don't ever have kids

Apparently I was wrong and its 2 and a half years old

you're right though, beat the shit out of the child when they're young and they'll learn their place

And the scar will only be there permanently

That's not possible, at the age of 3 and under your brain is not developed enough for that

A child under the age of 4 is literally incapable of making memories so that is the dumbest you can do you'll scar him and still won't understand

That kid is literally incapable of making memories letting him learn is impossible
