Prep warning
Macadamia is a tree nut, one of the major food allergens, so it's introduced on its own in a small amount early in the day, with a few days before the next new allergen, watching for any reaction such as hives, swelling, vomiting, or trouble breathing. Introducing tree nuts in a safe form from around 6 months, rather than delaying, is the current general guidance.
Choking notes
Whole, chopped, and halved nuts are among the highest choking risks for young children and are generally kept away until about age 5. Macadamia is given only as smooth butter thinned until it's no longer sticky, or as finely ground nut mixed into food. A thick spoonful of nut butter can also block the airway, so thin it before serving and keep meals supervised and seated.
How to serve by age
6-9 months
Whole or chopped nuts are a serious choking hazard for babies, so macadamia is given only in a form with no hard pieces: smooth macadamia butter thinned with water, breast milk, or a purée until it's no longer sticky, or finely ground nut stirred into oatmeal or yogurt. A thick blob of nut butter is itself a hazard, so always thin it.
No pieces at all. Thinned smooth butter or fine ground nut mixed into a soft food. Never whole, chopped, or halved.
9-12 months
The same forms continue: thinned smooth macadamia butter or finely ground nut worked into food. Whole and chopped nuts stay off the menu because the choking risk is unchanged. Keeping allergen exposures regular once the food is tolerated is the usual approach.
Still no pieces. Thinned butter or fine ground nut in a soft food. No whole or chopped nut.
12-18 months
Ground macadamia, a thin smear of smooth butter on a soft carrier like toast, or nut flour baked into food all work. Whole and chopped nuts are still not given to a toddler, since they remain a choking hazard well past this age.
Ground nut or a thin layer of smooth butter on a soft food. No whole or chopped nut. If a crunch is wanted, crush or flake it fine.
2 years and up
Ground or finely flaked macadamia and thinned smooth butter stay the safe forms through the preschool years. The one age-related change is that whole nuts are generally considered fine only from about age 5, once a child chews reliably; before that they remain a choking hazard.
Ground, crushed, or flaked, or as thinned smooth butter. Whole nuts only from about age 5.
