I will never forget the sound of that glass pitcher hitting the tile floor.

It was not the crash that stopped my heart. It was the tiny voice that followed it.

‘Please, Mommy, I’m sorry.’

My seven-year-old daughter Hannah was sitting in a puddle of cold milk, her hair dripping, her little arms wrapped around my baby boy Luke. And standing over her was my wife Melissa, the empty pitcher still raised in her hand like a weapon.
