Dude, stop sitting on me.

Children always want what the other kid has.  This simple, irrefutable fact has sparked many a playground tussle, been the impetus for thousands of swapped lunches, and forced millions of parents to listen to an endless barrage of "please, please, pleeeeeeease!!!" in toy stores all over the world.  Toddlers, I am now discovering, are no exception to this rule.  They swipe each other's toys (and whack each other over the head with them, if you're not quick enough to stop them), steal food right out of the mouth of the unsuspecting tot next to them, or - in the case of Ollie and Ava - refuse to find a place to sit that the other one isn't already in. 

I love that fact that he's just decided to sit on top of her in this one. 
What's really funny is that she doesn't seem to care.

And people wonder why I never leave the house without a camera.
