It’s impossible!
Mine always want extra drinks, more food, less food, different food, different cutlery, extra sauce, they like this, don’t like that. I’m up and down ten times.
It’s so stressful there’s no point in trying. It’s easier to just sort them out and then eat later. I don’t know how a whole family can sit down to eat together at the same time and actually finish their meal and enjoy it.
