No honey of any kind should be given to infants under twelve months.
Honey can contain Clostridium botulinum spores, which an infant's immature gut flora may not suppress, and infant botulism is a rare but serious illness. National food safety and public health agencies in the UK, EU, United States, Australia and New Zealand give concordant advice: no honey before twelve months, in any form. The spores survive heat, so cooking, baking and pasteurisation do not remove the risk.
What this does not claim: This is not a claim that honey is unsafe for anyone over twelve months, for whom it carries no comparable risk. Nor is it a claim about how common infant botulism is — it is rare, and the guidance is precautionary because the consequences are serious rather than because the probability is high. The traditional practice of giving honey to newborns is recorded on this page as a custom that exists; it is not endorsed, and the age of a practice is not a safety assessment.
