Time flies when you’re pulling yourself across tiles.

One day, you’re nursing your brand-newborn in your bed at home.

The next, (or 5.5 months later) you turn around for under a minute only to turn back and realize your baby is not where you left her, but rather pulling herself at a steady pace across the floor, reaching into the bottom shelf, pulling out a basket of toy cars, and sucking on one.

In the blink of a childhood.

Koala update: Seven months.

They grow up so fast. They grow up so fast. They grow up so fast.

Dammit, I’m surrounded by cliches. It’s getting kinda repetitive.

But I’ll take a cribful of cliches for all the milestones Koala has experienced in the last month.

He worked really hard to sit – every day, one leg under the tush, push ups… And then after a while, sit he did… Man, when he finally got it – what a look of satisfaction. I don’t think I’ve ever worked so hard to accomplish anything in my life (except maybe sitting). And all the while he worked on sitting, he worked on moving, too. And then a couple days ago, wah! He was one hand in front of the other, moving towards Papa. These last few days have held many surprises for newly-crawling Koala, as well as many surprises for various home furnishings. God help you, potted plants.

And all the while he’s been crawling, he’s been picking up a leg as if to stand. That’s the point where I’m like, whoa, cowboy. Not so fast. Mama hasn’t childproofed the kitchen yet.

But crawling has opened all new doors for Koala. Or should I say floors? Speaking of the kitchen, he has begun his licking the floor-under-the-fridge immunization program. We’re all very proud. All wonderful things, yes. But what about the teething front? Notes from the teething front:

It’s rough out here on the front lines… of the bottom gum. The parentals are hallucinating as they wake up every 2 hours to rub bottom gum with Orajel and then fall back asleep.

Just in from the teething front – Right bottom tooth has cracked through! Repeat, right bottom tooth has sprung!

Report: Right bottom tooth has sprung after an excruciating and sleepless and excruciatingly sleepless week.

That was the beginning of the month. On the eve of the seventh month, left bottom tooth has begun its trouble. Always on a weekend, folks. This kid cracks teeth on weekends. But the very best development this month: The first major syllable milestone. Out of nowhere, laying on his back, staring up at the ceiling, Koala burst out into a chorus of da da da da.

They were soft sounds, angelic, cherubic syllables I wanted to hug for a long time. Da da da. It just rolled off his tongue. It was probably as good as the first smile and the first laughter. Of course, he communicates in all sorts of ways, but this just feels like the beginning of a higher communication, a human communication.
