Destroying / Instantiating Child Game Objects

I have been using:

Destroy(gameObject)

to destroy objects until now, however, is it possible to destroy only certain child gameobjects. For example:-

Robot (parent)

Head(child)
Body (child)
Legs (child)
Arms (child)

is it possible to destroy only the “Head” child object?

and similarly to instantiate them?

Yes, get a reference to the desired object (using Transform.Find or whatever) and destroy it.
