Growth discovery by mommy - keeping up with big sister now

On our little home growth board, we measured Lila and Ian the other day and I realized something important. Ian and Lila are now growing at the same rate. She's always been very tall for her age and now he's just keeping up the pace with her. Is this because he's being pushed by the GH to an over accelerated rate? Or has it just taken care of his deficiency and brought him to his true potential growth as it should have been had all been balanced at the beginning? While I've been freaking out a bit by Ian's rapid growth in the last year, maybe it's just getting him to where he should be. 

We see Dr. Geffner at CHLA in a month and I can't wait! He's supposed to be "the doc" when it comes to endo and I'm so anxious to hear what he thinks about my sweet guy changing sizes every few months. Just as his sister did, but very unusual for him. We'll see.
