Believe me at any time will stop doing what I call the "Bur mode of why?" And you will miss it.

My daughter did not stop doing it when I was between 5 and 6 years old.

Now your questions and conversations are much more fluid and does not fall into the loop, which used to lead us to very crazy and fun answers.

Something I used to do was answer the first with coherent context. After the Quito "why?" I began to invent fun and crazy things, which finally led us to a moment of high doses of laughter.
