Step 1: First tiny taste
Offer a small taste of thinned smooth Brazil-nut butter. Watch for concerning symptoms such as hives, swelling, vomiting, or breathing trouble, and seek urgent care if those occur.
Brazil nut is a tree nut and a priority allergen. Tree nuts can be introduced with other complementary foods around 6 months. Never give whole Brazil nuts. Offer a thin, infant-safe Brazil-nut form as a single new food. If your baby has severe eczema or a prior immediate food allergy, talk with a clinician before introducing highly allergenic foods.
Use only infant-safe forms: smooth Brazil-nut butter thinned with water, breast milk, formula, or a tolerated puree. Never offer whole Brazil nuts, Brazil nut pieces, or thick sticky spoonfuls of undiluted Brazil-nut butter. Always supervise eating.
Offer a small taste of thinned smooth Brazil-nut butter. Watch for concerning symptoms such as hives, swelling, vomiting, or breathing trouble, and seek urgent care if those occur.
If the first taste was tolerated, gradually offer a larger amount of the same preparation at a later feed.
If tolerated, keep this food in the diet routinely as part of complementary feeding.
Complementary foods are typically introduced around 6 months of age, when the baby shows developmental readiness (for example, sitting with support, good head control, and swallowing food rather than pushing it out). Introducing solids before 4 months is not recommended.
Once your baby is ready for solid foods (typically around 6 months), tree-nut foods such as thinned Brazil-nut butter can be introduced with other complementary foods. There is no evidence that delaying common allergens such as tree nuts prevents allergy.
Never feed whole Brazil nuts or Brazil nut pieces to babies — they are a choking hazard. Use infant-safe forms such as smooth Brazil-nut butter thinned in puree, breast milk, or formula. Avoid thick sticky spoonfuls of undiluted Brazil-nut butter.
If your baby has severe, persistent eczema or had an immediate allergic reaction to a food — especially a highly allergenic food — talk with your child’s pediatrician about how and when to introduce highly allergenic complementary foods such as Brazil nut.
