Addison's one year stats

I took Addison in for her one year check-up on Tuesday, here are her stats:

weight: 20 lbs 9 ozs (45th percentile)
length: 28" (15th percentile)
head: 18 1/2" (92nd percentile)

What's up with this? How in the world can we have a baby that's so short? Surely she'll grow drastically...right? Here are Trinity's and Emory's from one year for comparison:

Trinity
21 lbs 11 ozs (60%)
30 1/2" (90%)
head: 18 5/8" (95%)

Emory
20 lbs 15 ozs (48%)
29" (50%)
head: 18 1/2" (92%)

So it's established, our girls have large heads...it's because their brains are abnormally large on account of their incredible intelligence:)
Emory's three-year check up is in a couple of weeks, I'm eager to see how much she's changed in her stats!
