More and more parents are using melatonin to help their children sleep - but there is little research on the long-term effects.

So, what do we know about the risks and is it ok to give it to children as an aid to help sleep?

James chats to Paul Gringras, professor of children’s sleep medicine and neurodisability at Guy’s and St Thomas’ NHS Foundation Trust and Vicki Beevers, chief executive of The Sleep Charity.

Also this week, resident GP Margaret McCartney on the potential promise - and peril - of doctors using AI in the NHS, and should you eat your placenta? We hear from a dietician on whether there’s any evidence it’s good for you.
