I don't remember a name for it, but the rule goes something like: young kids believe that once something is damaged, it is damaged forever and it can not be fixed in any way.
The textbook's example: they don't want pickles on a hamburger. You take the pickles off, but they cry and scream because the hamburger is ruined forever! They become instantly happy once you fix them a new hamburger, (or pretend to fix a new one, like I do.)
Another example: a toy breaks. The child is inconsolable even though you fix the toy. The child thinks it's damaged forever. An emtion coaching parent might say, "Do you think it's ruined forever?" "mm hmm" "I'm sorry, that makes you so sad." "mm hmm" "It's sad when toys get broken. You love that toy."
Luckily, I learned this little tip when my son was in that stage. It is one area where I was able to have patience and tolerance in situations that appeared on the surface to be absurd.
Have a great day!
