Words, Words, Words

Can I just say that it completely boggles my mind the amount of words that Alex can say?

off and on (both sound like "ah" but he uses them in the right context)
boom! ("boo!", whenever he falls down)
pull ("puh")
mama
daddy
hat ("ha", a less cute, but more intelligible version than "tah", which he used until recently)
cheerios ("che-os")
truck ("tuck")
binky (bi-ee")
yum ("um")
no
nose ("no")
eye
tongue ("tuh")
book ("buh")
up ("uh")
down ("dow" - used often in conjunction with "boo!")
door ("tor")
blanket ("bla-ee")
light ("li")
shoe ("zhoo")
tickle (one of his first words, it still sounds like "dooka")
pot ("pah")
ball ("bah")
that ("tat?", when he wants to know the word for something)
dragon ("dah-on")
toe
block ("bah")
computer ("poo-uh")

I know there's more, but this list just amazes me. Yesterday (I swear that it was last week, at the most.) he was just a helpless newborn, bleating out his needs with crying. Today he pointed at the top of the fridge and and said cheerios. It blows my mind.
