What is up with Ethan?

I really don't understand what is going on with Ethan. He will get sick once, lay around for a little bit, then will be running around like nothing is wrong. We are going to the doctor for his well visit. So I'm going to ask the doctor about this too.

Random pictures from last week.

Ethan: This is the proper way to clean your gun

Preston: locked and loaded. Now we are ready to take over the universe!

The cow is still around.

Mommy life isn't fair. I can't take over the universe without my gun.
