Brooklyn vs. Gavin

Brooklyn walks past Gavin and taps him on the head

Gavin: Booklyn, don't tease me!

Brooklyn: I'm not teasing you, I'm petting you!

Gavin: Don't pet me, I'm not a dog!

Brooklyn: I know I'm just pretending you are.

Gavin: "Mooom, Booklyn says I'm a dog!

Since when did my not-so-baby boy grow up and start having intelligible conversations with his older sister. I think I'm just having a hard time, since he'll be turning three at the end of this month. The past three years have gone by so fast and Gavin talks so grown-up I can't believe it...but you can't stop time, I just need to enjoy the journey.
