Dd2 is 2.4 she has an awful habit of when you open a door in the house she sticks her finger in the hinge bit so obviously when the door shuts ( they're fire doors so shut automatically) it traps her finger. It hurts her badly as fingers are so small and she's done it again today resulting in screaming and badly swollen finger. She did it once on patio door and dh didn't realise and he slammed door shut cue blood tears and a trip to the docs.
I'm thinking maybe some sort of sensory seeking as she likes touching very hot things as well but I'm stumped if I can think of a way to stop this one
