This is Owen's new 'angry' face. He makes it if he's frustrated or angry. It comes complete with huffing and puffing really fast through his nose.
If he's really frustrated
He purses his lips together really tight and blows - creating a spit-bubble ball that runs down his chin.
It's probably the funniest thing I've ever seen. And it's so hard not to laugh when he does it. :)
*sorry about the blurriness - he was moving a lot and it was low-lighting, but I had to catch this on camera!
