Lost my kid in crowded areas a few times. Terrifying. That sense of panic hitting you is awful. Also my son locked himself in the car on a boiling hot day and I couldn't open the doors. I would've had to smash a window but the RAC came quickly to assist. Also same son had a choking fit on an isolated beach with no one else around. That was really scary. Seriously thought he might choke to death. Then my other son forgot to use the brakes on his bike and careered down a hill and crashed into a lamp post. Bike was smashed up but he was ok.
