Taoiseach Leo Varadkar has said that plans have been put in place to care for Lisa Smith's child when she and her daughter are returned to Ireland.
The Defence Forces and the child and family agency TUSLA are involved.
The 38-year-old former member of the Defence Forces is being detained by Turkish authorities and is expected home in the next week.
Garda Commissioner Drew Harris also said that he presented the plans for Ms Smith and he was satisfied they were appropriate and proportionate.
He also said Ireland did not need a deradicalisation programme because of the relatively small number of Irish people returning from conflict zones.
Mr Harris said the numbers returning here were small, Ireland was not facing the same problems as other European countries, and that the gardaí were dealing with each case individually in a bespoke manner.
An Garda Síochána will have the primary responsibility for Ms Smith when she arrives back in Ireland.
Ms Smith converted to Islam and travelled to Syria to join the Islamic State group in 2015.
She has denied she was involved in terrorist activities there, but is now the subject of a criminal investigation and will be interviewed by gardaí when she returns.
Mr Varadkar, who was at the graduation of almost 200 new gardaí in Templemore today, said it would not be fair to expect Turkey to hold her forever, but her two-year-old daughter is also an Irish citizen and her welfare is paramount.
The Taoiseach also said plans have been put in place for Ms Smith and her child, and that the child and family agency TUSLA, the Defence Forces and gardaí are involved.
