Adults
Criteria for applying as an adult:
Are of full age (aged 18 or over, or if aged under 18 you are married)
A minor (child) is someone aged under 18 who is not married at the time of application. A child cannot make the application by themselves. The application must be made by their parent, legal guardian or a person acting on the child’s behalf ‘in loco parentis’.
The different types of application that can be submitted are:
If one of the minor’s parents has already been naturalised (use Form 9)
If the minor is of Irish descent or has Irish associations (use Form 10)
If the minor was born in the State after 1 January 2005, and was not entitled to Irish citizenship at the time of birth, but has since accumulated 5 years’ reckonable residence (use Form 11).
Long story short, he can't do anything now unless he has Irish descent/associations. As naturalization takes a long time. he'll be of full age (18) before you'll be naturalized. Get his documents ready and make sure you abide by the conditions around the time of his birthday, I'd say.
