Do you think it's right that I asked my kids to help pay for the takeout we ordered?
That depends. How old are your kids?
They're 11 and 9.
That's pretty young for them to be paying for their own food. They're too young to even have jobs. As the parent I think you should be paying for your kids' food.
Yeah but I pay for all the other food they eat?
I'm sure you do, but that's your responsibility as a parent. Kids shouldn't be expected to pay for their own food, especially when they aren't even old enough to work yet.
