Say the name of the food
“This is pear.” A plain name is enough. You do not have to say it is yummy or special.

The same name every time
Use the same name every time. Toddlers learn the food and the word together.
Pear, not “yummy special surprise.” A plain name is something they can say back later.
Once is enough
Say it when the plate arrives. You do not have to repeat it every bite.
If they say the name, answer and move on. The rice is still there to eat.
Foods that need a true name
Say “chicken” only when the diet includes meat. Say “egg” only when egg is part of the diet. Do not give a gentle nickname to a food that should stay off.
If milk is an allergy, do not call a cheese sauce “the yellow one” and hope. Name what is off, and leave it off.
A sentence you can say
