Tyler Says "NO"

Tyler is nearing his 15 month birthday, and he has a handful of very useful, new words. He can say, "baby", "bubbles", "bye bye", "bye bye bubbles", "hi", "cheetah (likely to be quite useful, I am sure)", "agua", "aja (over there in Spanish)", "mommy", "papa" and now, my ultimate favorite, "NO". Here is a rendition of Tyler practicing his "no's".
