a fine child for his age

[Tinkerbell]

That evening the queen said to Keo, who was growing to be a fine child for his age:

"I wish you'd run across the bend and ask your Uncle Nikki to come here. I have found a strange plant, and want him to tell me if it is good to eat."
wise for his age?

It's unclear what "fine" means here. You'd need to get the meaning from the context: what is special about the child for his age? It might mean wise.
