The family table can hold more than one diet
One person can eat meat while a toddler’s plate stays vegetarian. Serve their plate from the parts that fit.

One clear sentence
Tell anyone who feeds them the diet in one sentence. “No egg, meat, or fish” is clearer than a long explanation at the table.
Serve the child’s plate from the rice, vegetables, and other foods that fit. The adult plate can be different.
Shared spoons
A shared spoon from a meat pot or a cheese sauce changes the child’s plate. Use a clean spoon for their portion.
Milk allergy means their serving skips cheese and yogurt even when the table is full of both.
No pressure to match
They do not have to eat what the adults eat to be part of the meal. The familiar food keeps them at the table.
Change the saved diet in the app when the child’s diet changes, so the next week matches the house.
A sentence you can say
