"That's what I'm saying!"

Kyron has been adding that phrase after most of his sentances now adays. It's pretty halarious. Today he was playing with his puzzle and saying "I'm a big boy" and I said "Yeah? You aren't a little boy anymore?" and he said "No I'm big like a GIANT" to which I said, "Oh wow, like a giant? Then what am I?" as I stood up and looked down at him, he said, "You a T-rex!" Ha ha, love it!
