I love how Tyler refers to himself in third-person voice, and with a nickname.
Ty do it.
Baby touch Ty cheek.
Ty kiss Dada arm.
No baby! Ty toy.

The other day while Grandma & Kristin were visiting, he said the longest sentence I've ever heard. It was shocking hearing the syllables pour out of his mouth. He said "Ty put straw in basket, Mama." Now that was a mouthful. It may not make sense in writing, but the context of seeing the crazy straw stuck in the net of his basketball hoop made sense out of the whole sentence.

As he's beginning to repeat everything he hears, I'm beginning to wish I had a far broader vocabulary to expose him to. Also, hearing him repeat my words makes me realize how often I'm barking orders around:
No eat trash, Chili.
No cry, Baby.
Shawn, wake up.
This last one always cracks me up. To hear him call his dad by his name is one thing, but Tyler says his name the same way I do when I'm hollering at him from down the hall.
