“They’ll feel more independent” - seriously? Gads. Yes they all need to be more independent and out of control and tyrannical. I’ve watched my niece fix her son macaroni and cheese or French toast or grilled cheese while everyone else was eating the actual dinner that was prepared, to avoid the inevitable temper tantrum over whatever the meal was.
The tyranny of the urchin. Ridiculous.
As with many situations, there can be a happy medium between fomenting a tyrant and cultivating a neurotic robot.
Take what you want, but eat what you take, and provide at least something at the table that everybody can choose from (including the youngster) that the youngster will accept. Many foods have a more intense flavor to children than they do to adults.
