Early last year, we began marking SteelyKid’s height off on a door frame in the library. She occasionally demands a re-measurement, and Saturday was one of those days. Which made me notice that we now have a substantial number of heights recorded, and you know what that means: it’s time for a graph.<\/p>\n

The “featured image” above shows the results, and I’ve stuck in a zero-day point using her length at birth. The solid line in the graph is a linear fit to the data, because nothing could possibly be wrong with that. According to the fit, we can project that she’ll reach a height of 3.0 meters a few months before her twentieth birthday, and since the R2<\/sup> value is 0.99, you know that’s solid science.<\/p>\n

Her current height, for the record, I rounded up to 44.5 inches. And if you want to see just how big she’s gotten, here’s a photo from an after-dinner trip to the playground at what will be her school in just a couple of weeks, when she starts kindergarten. Yikes.<\/p>\n

I got The Pip to stand by the door frame on Saturday as well, and his official height was 33 inches. As it’s a single data point, though, it’s not worth graphing– you’ll have to wait until we accumulate more data before we can compare the two in a truly scientific manner…<\/p>\n","protected":false},"excerpt":{"rendered":"
