This time last year I travelled to the Bekaa Valley in Lebanon to see how Unicef, the world's leading children's organisation, is keeping Syrian children safe and warm as the temperatures plummet. Nothing could have prepared me for the heartbreaking situation I encountered; the conditions for families living in these informal camps were just horrendous. It's not somewhere that anyone should have to call a home, especially not a child. The over-crowded and unsanitary conditions need just one storm to set off a terrible chain reaction. The cold weather already makes children susceptible to respiratory infections like pneumonia.
