You cooked it, you plated it, you called them to the table — and now you're standing there holding a bowl you can't hand over. Two minutes. Four minutes. They're already on the floor.
So you do what every parent does. You blow on it. You stir it. You split it into two smaller bowls to spread the heat. You add cold water and ruin it. You test it with your own lip, decide it's fine, hand it over, and thirty seconds later they're crying because it wasn't fine.
And it turns out the blowing wasn't a great idea either. Paediatric dentists advise parents against blowing on a child's food, because it can transfer saliva — and with it, the bacteria that cause cavities. Most parents have never been told this. It's the one cooling method everybody uses and nobody questions.
Meanwhile the food is going cold on the other end, they've lost interest, and half of it goes in the bin.
