Constantly Asking "Why?"
An endless stream of "why?" is frustrating, especially when you've already tried giving clear, logical explanations for each question.
How to deal: Asking "why?" shows that your kid's curious and interested in the world around him. Sure, sometimes he does it to get a reaction, but most of the time he genuinely wants an answer. Issue an answer for five questions, and then redirect his attention. It'll stop the pop quiz ... for now.
