On: Cancer Patient Effectively Donates A Life-Saving Organ--To Himself

So they mention this being used for kids' surgeries. Would a replacement trachea grow with the rest of the body though?

My only-slightly-educated guess based off what I've read on this (read a few mentions of this story over the past week) is that while the child-sized trachea wouldn't just stop working/become disconnected, most likely there would be a later adult-sized replacement.
