ELI5: If a child loses a limb, and it's successfully reattached, can the limb still grow?

I'm talking about something small, like a finger (but more than just the tip of the finger). 

For example, if a child loses a whole finger in an accident, but then the finger is reattached, will the finger always remain the same size and appear deformed? Or is there any chance that it could grow as normal *after* being reattached?

I thought I could easily google this, but I'm not finding what I'm looking for.

(In case anyone's wondering, what made me curious is a documentary I watched about people who lost limbs during shark attacks; none of the victims were kids though).

It depends on how clean the separation is, how the limb was preserved (cooled) and how skilled the surgeon is. It will never stop growing. If it is attached successfully and is still alive then it will continue to heal and grow as usual. And it does not matter if it is kids or adults. Sharks do tend to tear the limb off instead of a clean cut and they tend to go for larger limbs and even swallows pieces of it. So it is very rare to get a good enough limb to reattach after a shark attack.
