How smart IS this girl?

So a couple of hours ago, Tara was tossing around her little nerf football; and said to me "I want to play with this at the playground." I told her that it was cold, and that Liam was still too little to take outside quite yet. She looked at me and said "I know, he's tiny. You stay here with little Liam, and daddy and me will go to the playground." (So funny!) I called Sean at work to inform him that little miss had plans for him once he got home...
