I would respond to any child of any age (as a parent to child, that is) by trying to figure out what they want, and doing everything I can to help them get it. If the child is angry, I'd keep helping them get what they want. Trying to figure out why the child is angry might be intrusive and make things worse, I think.... children often can't answer the questions of ‘why' that parents/adults
pepper them with, not having the words to explain what is in their minds or whatever. We make our best guesses and keep at it.
Could you please explain to me what "pepper" means here?
