Taoiseach Micheál Martin told the Dáil they have worked out the situation, despite the lack of specific maternity leave for politicians.
A Citizens' Assembly is set to recommend a long-term solution during the summer.
Minister McEntee said: "Women and men should know that having a family is not an impediment to a career in public life.
"Just as girls of my generation looked to the strong women who came before us for inspiration and guidance, those of us in politics now have a responsibility to make it easier for today’s girls to fulfil those dreams and ambitions.
"I and my colleagues in Government are determined to change the current system for the next generation."
