Having three children to look after meant it became too demanding for Yaz O'Connor to mind them and also work part-time.
So she gave up her job in social media management, for now.
She and her partner Billy Nolan, a self-employed builder, are parents to Leah (8), David (4) and Sabrina.
Ms O'Connor says she is relieved they only have one child in school, such is the expense.
"We are not looking forward to when the next starts. It is going to be very expensive, especially when they reach secondary school where it costs up to €1,000 per child."
But she has no plans at the moment to start a savings fund to help pay for the cost of the coming years of education.
"I can't afford to put money away at the moment. I will deal with it when it comes," she says.
The Dublin 15 resident, who blogs at Glittermamawishes.com, puts a lot of effort into keeping a lid on back-to-school expenses for Leah, who is heading into third class soon.
She estimates the books will cost €80 alone, even though she avails of a book rental scheme in the school. There is another €50 needed to pay for arts supplies and photocopying.
When it comes to uniforms, she is in favour of using generic clothing and sowing on crests.
She realises the school needs funding and is prepared to help out when there are sponsored walks and cake sales.
