I hope you're well. I am writing to you from the BBC where we are producing a landmark series for BBC Two all about the British family. It is a four-part social history series in which each episode will look at a different theme. The series is being presented by Kirsty Young, presenter of Desert Island Discs, who will travel around the country meeting both families with particular stories to tell as well as academics and professionals, with a view to building up a comprehensive picture of the changes the British family has gone through in the last 60 years.

The fourth and final episode in the series is all about children and childhood, and we are keen to speak to people who live in a '3G' family - a household made up of a number of generations. We would like to hear from people who find themselves caring for their children as well as their parents or parent, something which I have read has been termed the 'sandwich generation'. Whatever your experience of living in a household with three or more generations, the BBC want to hear from you.

If you have a story to tell then please get in touch with Jennifer Forde at the BBC. You can call on 020 8008 5667, or email jennifer.forde@bbc.co.uk. We look forward to hearing from you.
