When can babies have sesame? Is sesame a common allergen? How to serve it safely Keep it in rotation FAQ

01When can babies have sesame?

Like other common allergens, sesame can usually be introduced around 6 months, once your baby is eating solids and showing readiness signs — sitting with support, steady head control, and interest in food. If your baby has severe eczema or an existing food allergy, check with your pediatrician about timing first.

Already started peanut?

Sesame is a natural next step. See the full order of operations in our guide to introducing allergens.

02Is sesame a common allergen?

Yes — sesame is the ninth officially recognized major U.S. allergen (added under the FASTER Act in 2023), and sesame allergy is increasingly common. Introduce it on its own and watch your baby after the first taste.

03How to serve sesame to your baby safely

Choking hazard

Whole sesame seeds are tiny but can be awkward dry; use smooth tahini (sesame paste) instead, thinned. Treat tahini like a nut butter — never thick globs.

  1. Use smooth tahini (sesame paste) rather than whole seeds.
  2. Thin it with warm water, breast milk, formula, or a familiar purée until runny.
  3. Offer a small taste on the tip of a spoon, then wait ~10 minutes before offering more.
  4. Watch for about 2 hours, earlier in the day, when your baby is healthy and you’re at home.

04Keep it in rotation

Once sesame goes well, keep it in your baby’s diet regularly — about twice a week. Tolerance is maintained by repeated exposure, not a single taste. Working through all nine allergens? Our free allergen introduction schedule keeps sesame, peanut, egg, and the rest organized.
