It's been some time since he started to watch other people Youtube videos, probably a year or so. He watches adult people creations. He copies them first and then applies the ideas to his new creations.
I didn't teach him anything about making videos so this is his very first attempt to record his instruction. Pretty funny when Nathaniel (3,5) tries to have his few words here and there.
Eaton loves to spin all kinds of tops so he was excited when he came up with Lego one. He always creates duplicate for his brother to play with.
You can see that Eaton has a tendency to repeat a sentence when he is interrupted. Sometimes that happens many times ;-)
Here is the video:
I guess we need to work more on how to record movies :-)
