When your kid has been sick and as you sit at the dinner table they show no interest in food, let it go.
If they manage to eat a few bites, don’t tell them to eat more.
If they tell you they can’t swallow it, believe them.
If they start to gag, for the love of god, don’t sit and watch.
If you ignore all this, at least do this, when you get them to the bathroom, trust that more is coming no matter what they say.
