Lately Nate has been experimenting. Not the blow your eyebrows off kind but the kind where he just recently discovered he has a tongue and different sound levels. He'll chew on his tongue and use it to make this hushed spitting/tongue kind of sound. I don't know how to explain so I have a video. He has also been whispering a lot lately. Kind of funny.
For awhile we were not sure what he was doing, however, we did notice that every time he would make the sound a squirrel outside would stop and listen. I think he may be communicating with them.
The video doesn't capture his best moments but you get the idea.
