You have a deadline in three hours and your daughter wants to play another game of hide and seek. There’s no more work on the Lockdown Distance Learning portal. Is it OK to give her a screen, and if you do, what should she do? In today's episode of User's Guide to Now, Dr Aleks Krotoski asks University of Cambridge's Dr Amy Orben whether screens mess with ours - and our kids' - heads. Her most recent research looked at the impact of screens on wellbeing, and discovered some surprising results. Aleks then turns to The Guardian's computer games correspondent and best-selling novelist Keith Stuart about what he lets his 11 and 14 year olds play, and asks for advice on quality games that kids of all ages will enjoy.
