naturalised irish citizen minor

Hi everyone
I am a naturalised irish citizen through my both parents who were naturlised now
I was naturlised when I was very young around 10 year of age
At the moment I am living in uk and lift ireland sine I became 19
Do I have sign a declaration to retain my irish citizen ship as I heard from some people
I lived most of life in ireland
When I first came to Ireland I was 3 years old.
I got naturalised through my parents when I was young. So basically I want to now what do I do I'm I going to loose my citzenship if I lived abroad more then 7 years without signing the declaration
It's surprising that's the only passport I use any ways.
