A short meal is allowed
Ten to twenty minutes is a long time for a toddler to sit. When they are done, the meal can end.

Short and calm beats long and loud
A short calm meal beats a long battle. Clear the plate without a lecture.
Set a rough end in your own mind. When they are done, you are done. The kitchen can return to the evening.
Done is a signal
A turned head, a played-with spoon, a “finished.” Believe the first clear one. Another five minutes rarely adds a happy bite.
Food can come back at the next snack. It does not have to come back as a negotiation.
What you skip at the end
Skip the summary of what they did not eat. Skip “just one bite” as the price of getting down.
If every meal is a battle to keep them seated, talk to your child’s doctor. Length is not the medicine.
A sentence you can say
“You’re done. We’ll eat again later.”
