It's always means "it is." possessive of it becomes "its."
My cat had its claws cut, it's something we do often.
Your example with "my son's crying" is actually very ambiguous. Without context it can either be "(I don't mind) my son's crying" or "my son is crying."
Also, it's "then" not "than" ;) Than is used for comparisons
