The election promise means parents would automatically receive a single payment of €280 once they register their child's birth.
Fianna Fáil is promising to double the child benefit payment for new parents for the first month after the birth of their child, according to the Irish Independent.
The party says that they hope the double payment would ease the financial burden of starting a family.
It's estimated that the new shift will benefit some 25,000 parents every year and will cost €3.5 million to implement.
The monthly payment of €140 applies to the parents or guardians of children under 16 years of age. It is paid for children under 18 years of age if they are in full-time education, full-time training or have a disability and cannot support themselves.
During the recession, child benefits were lowered to €130 from €166 during Celtic Tiger years. Since then, €5 has been added each year during the Budget.
It was also revealed in an interview with Extra.ie, that Fianna Fail is set to provide working parents with a substantial tax credit of €2,000 per child against the cost of childcare if elected to office.
The tax break will apply only to parents who pay childminders and will not go towards the costs of creches.
The party attempted to implement this in Budget 2016, but the shift proved too costly.
Fianna Fail will also extend the ECCE — Early Childhood Care and Education Programme — and seek to regulate the 20,000 au pairs in the country to alleviate the childcare crisis.
