For some reason or another, for a tiny little checkup with x-rays...we were shuffled into FOUR different waiting rooms, until finally reaching the room where we saw the doc and she went over K's stats. The difference in the length in her legs is about 1cm....anything over 2cm is cause for worry.
So we have to take her in once a year just to keep track on the measurement of difference. Then when she's a teen and almost done growing...we'll see what the next step is. Either everything will be fine, or if the difference is 2cm or more, then they'd have to stunt the growth in the longer leg. Eh, we'll cross that bridge when we get there.
