Opera Singer

Collin LOVES to sign.  Most of the time, he is singing songs he makes up as he goes based on what he is doing at the moment, what he wants to do or not do.  This is not just regular singing either.  He belts out the words like an Opera singer and does this for 5 or more minutes at a time. 

Here is a short video of an example of what I am talking about.  I am trying to read books to him before going to bed and he is distracted with Burke in the room.  This is what happened:

He does this in the car, while we are walking Burke, while I am cooking for him and....as you just saw, right before he goes to bed.
