Labour senator John Gilroy will leave the Seanad for the school run and experience what life is like for a mum of three.
The Cork politician responded to a bizarre online challenge by Waterford woman Andrea Galgey to spend an entire week in her shoes.
A number of production companies are expected to seek the rights to make a documentary of the exchange.
Ms Galgey - who is a single mum to three boys - said politicians' constant talk about "cuts" inspired the challenge.
"We were obliterated in the last budget with cuts. I thought if they really think that we all have been cut equally they should come and see how I live," she said.
"I am an ordinary person, some are a bit richer, some people are less well off.
"So if I am struggling it must mean that the majority of people around the country must be."
