Sir Michael Morpurgo on why a grandparent's role can be a tricky one

Anyone who thinks it's just the parents who raise a child these days is kidding themselves. For the vast majority of new parents, having a collection of willing grandmas and grandads on hand for advice/babysitting is not just helpful - it's essential.

However, that poses its own challenges. Where and how should grandparents get involved in the actual parenting of a child?

Sir Michael Morpurgo - the 75 year-old grandfather and renowned children's author who wrote War Horse - joins Steve and Rich to see if they can figure out the answer to that notoriously tricky question.

They also discuss just how dramatically the idea of fatherhood has changed since Sir Michael raised his own children and the remarkable lessons Sir Michael has learned from his autistic grandson.
