There's a documentary about Ireland running out of babies, Mary Berry is back, and Fleabag continues its singular journey . . .
Pick of the Day
Fertility Shock, 9.35pm, RTÉ One
In this one-off documentary journalist Dearbhail McDonald takes a look at why and how Ireland is running out of babies.
Irish people are having babies later and later, and when they do start a family, they’re having fewer children than ever before - in short, we’re not having enough children to replace ourselves.
McDonald explores how fewer children, combined with an ageing population is storing up a very real demographic time-bomb for Ireland.
