Invariably they want to know, " WHAT'S THAT? "
They can't wait to see what's inside.
It doesn't matter how many times you tell them, they will still ask over and over again as if it were the very first time they asked.
It's enough to drive you insane!

The good news is that like so many other things during their life this too shall pass.

One day you will wish they would ask you even something as simple as " What's That? " instead of leaving you with the feeling that they already know all the answers.
