There is nothing to “address” otherwise.
This “physical discipline” is illegal in most of the world. Make clear to SIL (have husband do if it’s his sister) that she is never to be violent with your child again and then NEVER leave a child with her. It is normal and natural for a child to be disappointed and difficult transitioning from a fun activity. She was probably a bit warn out. So what did this “discipline” teach her. Teaching is the meaning of discipline. It taught her that people love you are allowed to hit you. It taught her that people that are bigger and more powerful than you are allowed to hit you. Did it teach her one thing about how to transition away? Was it responsive to her developmental level? Obviously not. Healthy adults would validate her emotions and help her focus on the next thing.
