SteelyKid had her two-year checkup this morning, which means we got new weight and length measurements for her. It’s been a while since I did anything really dorky with her data, so here are a couple of graphs tracking her growth:
(Yes, they’re in English units, not SI. Deal with it.)
Using the rule of thumb somebody mentioned a while back that a person’s final height is double their height at age 2, this projects her to be a bit over 5’9″, so that’s a prediction we’ll be able to test in another fifteen years or so. There’s some fairly large uncertainty in these, though, especially today’s points, as she’s now strong enough to be difficult to hold down for an accurate length measurement. By next year’s check-up, we should be able to get her height while standing, and make a game of it.
In the last two years, she has increased in length by almost 75%, and her weight has gone up by a factor of 3.6. Kind of amazing, really.
The weight graph in particular shows a couple of plateaus. The 15-20 month plateau is probably due to the series of wretched colds she had this winter, during which she wasn’t eating much (the doctor she saw in December was concerned enough to schedule some weight-check appointments, hence the larger than normal number of points in that interval). Both her height and weight are at the 75th percentile, according to the chart I got from the doctor today.
I’d do some curve fitting to these, but I no longer have SigmaPlot at home, and trying to get anything reasonable out of Excel is too painful. Maybe later.
