I was totally blown away!! That's actually been his only two word phrase for a while, but he's never used it in that context. He usually says it when he's really wants something really bad, I'll pick him up and he'll point me in the direction if whatever it is, and say "Oh, I know" (almost like he's having the realization for me, lol). But this is the first time that he said it in a way that I knew that he knew what it meant. I totally melted!!
There should be a thread for the cute things our kids say to us.
