How to Serve Mayonnaise to a 6–9 Months Old

How to Cut

Not applicable—Mayonnaise is a spreadable condiment and does not require cutting. Instead, offer it in small quantities blended into purees or as a thin layer on soft, age-appropriate foods, like avocado or well-cooked vegetables to help introduce new flavors and healthy fats. Always use pasteurized, store-bought mayonnaise at this age to reduce the risk of foodborne illness.

Serving Instructions

At this age, mayonnaise is optional and should only be introduced after individual ingredients (eggs, oil, mustard) have been offered and tolerated separately. Offer no more than 1/2 teaspoon (2.5g) per meal and always use pasteurized, store-bought mayonnaise to minimize the risk of foodborne illness. Blend into vegetable purees or spread a very thin layer on soft foods. Combine with iron- and vitamin C-rich foods for an optimally balanced meal.

How to Cut

No cutting needed—Mayonnaise can be used as a thin spread or dip for soft finger foods like well-cooked vegetables, soft bread strips, or scrambled eggs. Use a small amount (about 1 teaspoon/5g per meal) as part of a balanced meal. Continue to ensure mayonnaise is pasteurized and store-bought to reduce the risk of foodborne illness.

Serving Instructions

Mayonnaise may be offered as a thin spread or dip for soft finger foods such as bread, steamed veggies, or poached chicken. Limit serving to about 1 teaspoon (5g) per meal. Use as a flavor enhancer and source of healthy fat, but balance with iron-rich foods (like lentils or beef) and foods high in vitamin C (like red bell pepper) to support absorption. Always monitor for allergic reactions.

How to Cut

Still no cutting needed. Mayonnaise may be used more freely as a dip or light spread, but maintain moderation—aim for no more than 1 to 2 teaspoons (5-10g) per meal. By this age, you can introduce mayonnaise as a component in sandwiches, wraps, or mixed into cold dishes like pasta salads. Continue to use pasteurized mayonnaise and monitor for any allergic reactions, especially if the child hasn’t previously had eggs or mustard.

Serving Instructions

Mayonnaise may be included in sandwiches, wraps, or as a dip for a variety of cold dishes such as pasta salad. Limit to 1-2 teaspoons (5-10g) per meal to avoid excess fat intake. Pair with a variety of foods, including those rich in iron, vitamin C, and fiber, to create a balanced and nourishing plate for your growing toddler. Continue to use pasteurized mayonnaise and monitor for allergies if relevant.
