MIRIAM O'Callaghan has said she won't be offering Prime Time co-host Claire Byrne any advice on her pregnancy.
Instead, the mother-of eight has given Claire, who is expecting her first baby in October, a present of a book she used through all her own pregnancies.
First published in 1975, Pregnancy was penned by Dr Gordon Bourne, a consultant obstetrician and gynaecologist at one of London's leading teaching hospitals.
"I would never impart advice but what I have done is give Claire a book which the journalist Peter Snow gave it to me when we worked together on Newsnight, and I was having my second child.
"It's a very old book which I had to track down through Amazon which gives very straightforward advice.
"If I was ever worried about a twinge or pain during pregnancy, I would consult this book and it would tell you exactly what was going on which was reassuring," Miriam told the Herald.
Famous for juggling children and her media career, the 51-year-old said she was "delighted" at the news that Byrne (36) and fiance Gerry Scollan were expecting their first child.
But said it had led to some light-hearted banter in RTE.
"People are blaming me, saying Claire is only working with me a minute, and I've already convinced her to have a baby.
"This had nothing to do with me," she joked.
But the two will be seeing less of one another in the coming months as Miriam departs Prime Time to host Saturday Night With Miriam.
The summer series kicks off tonight, with guests including Ruby Walsh.
The RTE star believes Walsh is a popular guest for an Irish TV show and has defended the use of local names on RTE shows, derided in a recent You Tube clip which contrasted big name guests dancing and rapping on Graham Norton's rival BBC show and audience members Irish dancing on Ryan Tubridy's Late Late Show.
"It's unfair to compare because stars like Will Smith, who Graham Norton had, don't cross the water to appear on Irish chat shows, but someone like Ruby Walsh is perfect for Irish TV because horse racing is so popular," she said.
Chef Clodagh McKenna, singer Damien Dempsey, and Irish actor Colin O'Donoghue are the show's other guests on Saturday Night With Miriam at 9.30pm.
