Isaiah is quite a little engineer. Daily, his papa asks him for an evaluation of the effectiveness/ user friendliness of some item in our home- the new fan, the vacuum cleaner, a remote control. He loves giving his full attention to studying how things work. We were outdoors recently and he found an interesting door knob to yonk on for a while. I told him "turn it down, Isaiah". He stopped, looked up at me, and then turned himself around like a regular hokey pokey.
Here is a video of Isaiah's new moonwalking/ "walk backwards" trick that he's really excited about.
