Sesame allergy in babies

Sesame is now recognized as a major allergen and shows up in tahini, hummus, and some breads. It can be introduced around 6 months, most easily as smooth tahini or hummus.

Safe ways to serve sesame

Smooth tahini thinned and stirred into food
Smooth hummus (which contains tahini) as a dip or spread

⚠️ Use smooth tahini/hummus, thinned as needed. Whole sesame seeds add little and can be gritty for young babies.

Signs of an allergic reaction

Hives or welts, unless they are only around the mouth with nothing else
Swelling of the lips, face, or eyes
Vomiting

If any of these show up soon after a food, stop that food and get medical advice right away
Call emergency services right away for swelling of the tongue, swelling or tightness in the throat or trouble swallowing, difficult or noisy breathing, wheezing, a cough that keeps going, or a hoarse voice
Also call emergency services for swelling of the lips or face that comes on suddenly or keeps spreading, vomiting that repeats, hives that spread over the body, skin or lips that turn pale or blue, a baby who goes floppy or is hard to wake, or signs in more than one part of the body, like hives plus vomiting

General tips for introducing allergens

Most babies are ready for solids around 6 months, once they can sit with support and show interest.
Introduce one new allergen at a time and let its watch window pass, about 3 days, before the next, so any reaction can be traced to a single food.
Once an allergen is tolerated, keeping it in the diet regularly is part of current guidance.
Offer allergens earlier in the day (not right before bed) so you can watch for any reaction.
If your baby has severe eczema or a known food allergy, talk to your pediatrician before introducing peanut or egg.
