I’m sure it’s a common pastime for parents to wonder what their kids will turn out like…. Will they like sports or music or books? Will they be hyper or laid-back or always curious? Currently, I’m just wondering about size.
You see, when we get Lincoln measured they always tell us what percentile Lincoln is in according to the “average kid.” When he was born, he was 7 lbs. 10 ounces, head circumference of 14 inches and 21.5 inches long. This put him in the 50th percentile for weight, about the 50th percentile for head circumference, above the 97th percentile for height, and less than the third percentile for weight-to-height ratio. That means that out of 100 kids, mine would be the tallest. I find myself being proud of the big numbers, like they are test scores or something. It’s funny, I never remember being happy about my larger-than normal cranial circumference, but I can’t help thinking that my kid is passing height and failing weight sometimes!
So, I wonder what these numbers mean looking forward?
At Lincoln’s 2 week check up, he was about 22 1/2″ (>97%), 8 lbs. 8 ounces (50%), head 14 3/4″(50%), and he was less than the 3rd percentile for weight-to-height ratio. At his 2 month checkup, he was 24 3/4″ (>97%), 11 lbs. 11 ounces (50%), head 16″ (about 60%), and he was less than the 3rd percentile for weight-to-height ratio again!
I don’t know how much these percentiles can change over time, but it certainly makes me wonder how he will grow up? Will he be a tall and lanky guy? Or will he beef up and come back toward those oh-so-average 50’s? If he stays in the same percentiles, when he is 3 years old, he will be 40.5″, 26 lbs., and have a head that is 19.5″ around.
But what about when he is an adult? According to the charts, when he turns twenty, above the 97th percent means at least 6 foot 3 (and his parents are 5’9″ or less). If he stays less than the 3rd percentile in weight-to-height, that means he would be under 123 lbs…. that’s one skinny tall guy! But, forecasting another way, if he stays around the 50 percentile in weight, then he’ll be about 155 lbs. Still a trim tall guy!
Lincoln’s 4 month check up is in a few days so we’ll see if the trend has continued. And to be honest, the appearance of cankles makes me think that he is fattening up some. You may think I have to be an engineer to get into numbers like that (and I am), but I think parents find real joy in their kids and their growth in all dimensions (which I do). No matter what Lincoln looks like, he’ll be great.
(Numbers were caluclated from a webpage here and some charts I downloaded. )
