I can't watch movies in which stuff happens to babies/kids the same way

I've just watched hereditary again, and I cried with the mother.

Possible spoilers !!

When I watched it the first time, I thought "owww...that's so so sad, I couldn't imagine what she went through". Or when I watched dumb horror/thriller movies, I thought the actresses were exaggerating.

Now I felt the mother's pain in my BONES. When she screamed "oh, it hurts so bad, I just want to die" I thought "what the heck would I do if I were in her position?" How would I react? I cried just thinking about it.

Now I refuse to watch movies in which things happen to babies/kids. Normal horror movies are okay. Horror movies with kids? Nope.
