The U.S. Census does extensive work to track what kinds of financial support children receive from separated parents. It looks like the latest tabulated results are from 2015. Can’t say I can interpret them very easily but appreciate reading all the different categories. I think that non-custodial parents spend as much on gifts as they do on food. And, either way, that might not be much.
I remember the check coming sometime in the middle of the month. I remember being called Child #2 and my older brother was called Child #1. I remember the bartering over who will get the tax deductions this year. I remember being left alone in the house with boxes of cereal and gallons of ice cream to eat. I remember eating from my Mother’s doggie bags from her dates. I remember my Step-Mother bragging about how decadent the restaurant was that she and my Father had recently eaten at. I remember my Step-Sister ordering the Lobster to screw my Father out of his money.
