They threw the food
Throwing is common when the plate is overwhelming or the meal has gone on too long. Take the thrown food away without a speech.
No speech
Leave a small amount of the familiar food if they are still eating. End the meal if throwing is the whole activity.
A lecture about the floor makes the throw the most interesting thing that happened. Pick it up. Continue or end.
Make the plate smaller next time
Less food, a shorter meal, the familiar food in reach. Throwing often means there was too much in front of them.
The new food can wait until a meal that stays calm. Do not put a full portion back to prove a point.
When it is every meal
Throwing once is ordinary. Throwing as the whole meal, every meal, is a reason to talk to your child’s doctor or a feeding therapist.
This page cannot name a feeding problem. It can tell you to shrink the plate and stop the speech.
A sentence you can say
“That’s down. Your rice can stay.”
