"Experting"

On and off recently Caleb will tell me that he has or is "experting" something. I have asked him what he meant but still wasn't quite sure until today. What he means is ORGANIZING something. For example, if he was stacking a pile of books he would tell me that he was "experting" them!!! :) Obviously, I will continue to encourage him to "expert" whenever he wants!! In fact, we desperately need to "expert" his bedroom...
