Allergen note
Tomato allergy is uncommon, but acidic tomato sauce can redden the skin around the mouth or irritate the diaper area; this is usually irritation rather than an allergy and fades quickly. For first tries, choose plain canned tomatoes without added garlic, onion or herbs so any reaction is easy to spot.
How to serve
From around 6 months, simmer canned tomatoes into a smooth sauce and stir a spoonful into mashed potato, lentils or pasta. From 9–12 months, offer soft chopped tomato mixed into rice, beans or scrambled egg; toddlers can share family pasta sauces and stews.
Preparation
Pick no-salt-added canned tomatoes and skip seasoned or sweetened varieties, which can be high in salt and sugar. Simmer them for 10–15 minutes to mellow the acidity, then blend smooth for younger babies or mash lightly for older ones.
Texture and choking risk
Canned tomatoes are already soft, but whole canned tomatoes have slippery skins and a firmer core. Chop or mash them, remove any tough core pieces, and supervise your baby sitting upright during meals.
Starting ages are typical guidance for healthy, full-term babies who show signs of readiness. Your paediatrician may advise differently, especially where there is a family history of allergy.
Track first tastes and reactions
Log when your child first tries canned tomatoes, note any reaction and see it in the allergen tracker.
