Keep the snack they always accept
The snack they always say yes to is useful. It is a food you can count on away from home and on hard days.

Do not retire the yes
You do not have to retire it to make them adventurous. New food sits beside it, not instead of it.
The apple they always take is a tool for cafés, parks, and tired nights. Keep it in the house.
Beside, not instead
At home, the accepted snack can share a plate with one new bite. Away from home, the accepted snack can be the whole offer.
Replacing it with a “better” snack they have never eaten is how a sure thing becomes a gamble.
Allergies still win
A favourite snack stays off if it contains an allergy. Find the yes inside the foods they can actually have.
Tell anyone who feeds them the name of that snack and the allergy in the same sentence.
A sentence you can say
“We’ll take the apple you like.”
