Is sleep is the ‘next feminist issue’? Well it is, according to one of the top women journalists in the US. Arianna Huffington has proclaimed that in order for women to get ahead 'we're all going to have to lie down and take a nap'. She’s putting her pillow where her mouth is, and has pledged to get a full night’s sleep every night this month. But is it true that women are second class citizens when it comes to getting their fair share of time under the duvet? And how do parents negotiate whose sleep is more important when there are babies to be fed? Kira Cochrane, from The Guardian, and Professor Jim Horne, Director of the Sleep Research Centre at Loughborough University, join Jenni to discuss the politics of sleep.
