The Children's Minister was informed about serious concerns regarding Hyde and Seek Childcare more than a year ago.
Katherine Zappone was also told at the time that the centre wasn't registered with Tusla, however the creche in north Dublin continued to be unregistered for another seven months.
In August 2018, Finance Minister and Dublin Central TD Paschal Donohoe forwarded a copy of a complaint he'd received from a constituent to Minister Zappone.
The constituent was a parent of a child who attended the Hyde and Seek facility in Glasnevin.
They parent, whose child attended the Hyde and Seek facility in Glasnevin, raised serious concerns about the facility, and the fact that it wasn't registered with Tusla.
They also described the centre as 'absolutely disorganised' and raised fears about the turn-over in staff.
In March of this year, Minister Zappone wrote to Minister Donohoe to confirm the centre was registered with Tusla on March 1st - 14 months after it began operating.
Fianna Fáil's spokesperson for children, Anne Rabbitte, obtained the documents under the Freedom of Information Act.
In July, an RTE Investigates documentary revealed concerning practices at Hyde and Seek's crèches.
