Congrats on you new addition!  Enjoy him while he is small (and can’t talk back) !

My daughter was not diagnosed until age 5 and we didn’t have our first bone age x-ray until age 7.

I’m not sure at what age they start the x-ray procedures, but that is something you can ask your endo.  Has his growth been an issue?  If not, I wouldn’t even worry about it for a while.  Just keep it in the back of your head for the future.
