Andrew's vocabulary at 21 months. :)

Cah: Car (said with a really heavy "kkkk" sound)
Doh-uh: Lights (I have NO idea where he got this; he just made it up, but anytime we go someplace, he points up and says it really loud over and over again.
Birds-uh: Yep, he still says this one all the time. He loves for me to read his Wonder Pets book and he continuously points to the yellow duck, saying "birds-uh"
Hotd: Hot. This is said when anyone is in the bathtub or near the stove.
Brrrrr: Brrr. (Cold). This is said when something is cold or if the floors are cold in the back bedroom.
Ah lee: All clean (we say this during bathtime).
Oh no: Oh no (said with a Wisconsin/Minnesota accent--occasionally "no" sounds like "noah")
Mo: More (usually said while whining to me that he wants more mommy milk)
Two: Two (said to me after I say, "one")
Mmmmmm: Food
Nom: Food (what can I say, the kid likes to eat)
uhWaWa: Water
Outside: (Outside)
Bah: Ball
Boon: Balloon (he screams this every time we go to the grocery store because they have graduation balloons and the like out)
Eeeeeeeeeeeee: Airplane
Ooooooooooooh: Blow dryer (or vacuum cleaner). He also has a word for "blow dry", and occasionally will say it, something like "die".
Dude: Dude
Joo: juice.
Coh: Cow (sometimes sounds more like "goh")
Drew: I think he's saying Andrew, but not 100% sure
Bee: Bee (like his Bee and Me book)
Gwa or Gwana: Iguana (from one of his animals books)
Bwid: Bridge (he learned this one the other day when we were at the picnic; there's a bridge you can walk over)
No: No (again, with a Wisconsin accent). Sometimes pronounced, "Noah"
And then of course, there's "Ah-dah" and "Mom"

I'm sure I am forgetting some, but this is here for my records now.

He's also become a fan of filling in the words in books. Two of his favorite books right now are Wonder Pets and Bee and Me. In the Wonder Pets book, there is a line that says, "Look a baby kangaroo! He's lost and wants his mama too", and he knows when that "mama" comes up, so he is ready to say it before I get to that spot. In the Bee and Me book, he loves the part where the boy has to shut the window, and the bee says, "Oh no". Andrew gets a huge smile on his face, because that is one of his favorite things to say. I will move on and keep reading, and he has to turn back to see that page again. :)

He knows things!

Words, that is. Andrew knows a lot of words. In the morning, Daddy tells me that he'll say, "Bluebods?" (our strange abbreviation for blueberries...it started a long time ago and for some reason we just stuck with it) , and when he says this, Andrew will crawl over to his high chair in anticipation. He'll then proceed to make a lot of squealing noises until he is up in his chair with "Bluebods" in front of him. So cute!

Daddy also said that yesterday or today he said, "Do you want to take a bath?", and Andrew crawled into the bathroom.

Tonight Daddy said, "Car ride?" and Andrew crawled towards the front door, fussing. We weren't going in the car, so then I had to distract him with something else.

Also, the 2nd day he had his new ball (my mom got it for him), we would say, "ball" and Andrew would go get his ball.

I love it!

Andrew also does this cute thing when he crawls around--he'll hum a little song. It goes, "m m m"....."m m m"... always sets of three. If I start doing it too, he'll smile and repeat. He has even done this while nursing!
