'The baby was swept away'

The North Sea Flood was exactly 60 years ago. Two and a half thousand people were killed - the majority in the Netherlands but hundreds more in the UK and at sea.
The waters were unstoppable - the result of a high spring tide and storms. Along the east coast of England 307 people died and tens of thousands had to be evacuated because their homes were devastated. It prompted a huge investment in flood defences in the years after.
But it is too expensive to create unbreachable defences along the entire coast - so it is still the case that difficult decisions need to be taken to decide which communities get protected and which do not, as Nicola Stanbridge reports.
