Why

Store-bought mayonnaise is made with pasteurized egg and acidified enough that it is not considered a raw-egg risk, so the classic worry does not apply to jars from the shelf. The real considerations are that mayo is calorie-dense with little else to offer, and egg is a top-8 allergen — though a baby already eating cooked egg is unlikely to react to mayo. Homemade mayo made with raw or undercooked egg is a different story and should wait.

How to serve it safely

Stir a small spoonful into tuna, chicken or potato mash, or thin it as a mild dip. Introduce alongside your baby’s usual egg exposures and keep portions small so the meal stays balanced. Avoid any mayo made at home with fresh raw egg, and refrigerate opened jars.

Warning signs to watch for

Egg allergy reactions typically appear quickly: hives, swelling of the lips or face, vomiting, rarely breathing difficulty. A baby who already tolerates scrambled egg is very unlikely to react to commercial mayo.

When to call for help

For hives, swelling, repeated vomiting or breathing difficulty, seek medical care urgently — breathing trouble is an immediate 911 (US) emergency. US Poison Control: 1-800-222-1222.

Common questions

Doesn’t mayonnaise contain raw egg?

Commercial mayo uses pasteurized egg and an acid treatment that makes it safe for babies; homemade versions with raw egg do not, and those should wait well past babyhood.

Can I give my 7-month-old egg salad?

Yes, if it is made with commercial mayo and the egg is fully cooked — just mash or chop it to a texture your baby manages, and keep portions modest.

Light or full-fat mayo for babies?

Either is safe; babies actually need fat for growth, so there is no need to choose light versions. The bigger point is that mayo is a condiment, not a main food.
