At a big, busy play area a few weeks ago with my 6yo DC when a distressed younger child (approx 3yo) came up to us, bawling their eyes out saying they'd lost their Mummy.
I comforted the child, had a good look around our immediate vicinity then took the child by the hand and went looking for their Mum. We found her quite quickly as she was looking for her child having become separated.
I thought no more about it until reading a thread on here where lots of people were saying under no circumstances should you ever touch a stranger's child. I thought, as adults, we have a collective responsibility for the safety and wellbeing of children.
What would you have done?
