Quick answer
Babies can eat star fruit from around 6 months, once they show signs of being ready for solids. Prepare it as shown below.
How to serve star fruit by age

6 months+
Soft-cooked spears, seeds removed, or mashed
Trim the dark edge off each ridge of a ripe star fruit. Cut it lengthwise along the grooves into long spears, one ridge each, and pick out the seeds. Peel off the waxy skin if you can. Steam or simmer the spears until soft, or mash cooked star fruit and serve it on a pre-loaded spoon.
- Size
- Spears about the size of an adult finger, roughly 6–8 cm long and 2 cm wide (2½–3 × ¾ in), or mashed.
- Check before serving
- Squash a spear between your thumb and finger. It should flatten easily. If it still feels crisp, cook it longer.
US and UK advice differ here. The AAP suggests mashed food or soft pieces no larger than ½ inch; the NHS suggests soft finger-sized pieces your baby can hold in their fist. Both agree the food must squash easily.

9 months+
Small soft pieces
Cut soft-cooked, seedless star fruit into small pieces for pincer-grasp practice, or stir them into oatmeal or plain yogurt (once dairy has been introduced on its own).
- Size
- Pieces no bigger than about 1 cm (just under ½ inch).
- Check before serving
- Each piece should squash flat between your thumb and finger, with no seeds.

12 months+
Thin slices cut small, or soft-cooked pieces
Raw star fruit is crisp and slippery. Slice it very thinly, cut each star into small pieces, and pick out the seeds. Never give thick star-shaped slices. If your toddler struggles with crisp food, keep cooking it soft. Offer a few pieces as part of a meal.
- Size
- Pieces about 1 cm (just under ½ inch), cut from very thin slices.
- Check before serving
- Check every piece for seeds, and make sure no thick or whole slices are left.

18 months+
Thin slices cut into pieces, or soft-cooked pieces
Serve very thin slices cut into small pieces, or soft-cooked pieces, seeds removed, as part of a meal or in fruit salad. Keep the portion small. Make sure your toddler sits down to eat, and stay with them.
- Size
- Bite-sized pieces about 1 cm (just under ½ inch), cut from thin slices.
- Check before serving
- Check for seeds and thick slices.
Always have your child sit upright in a high chair or at the table, and stay with them the whole time they eat. Keep to the size and texture for their stage. Every baby develops on their own timeline.
How to prepare star fruit
- 1
Choose a ripe star fruit that is mostly yellow. Rinse it under running water, gently rubbing the skin, and dry it before cutting.
- 2
Trim the dark edge off each ridge, and cut off both ends.
- 3
Cut it lengthwise into spears (6 months) or slice it very thinly and cut the slices into small pieces (12 months+). Pick out every seed.
- 4
For babies under 12 months, steam or simmer the pieces until soft, let them cool, and do the squash test. Don't add sugar.
How much to offer
Start with one or two soft spears, or a teaspoon or two of mash, as part of a meal with other food, not on an empty stomach. Your baby decides how much to eat: stop when they turn away or close their mouth. Keep star fruit to a small portion, never juice or a big bowlful, and skip it while your child is dehydrated or has vomiting or diarrhea (see the FAQ below).
Common mistakes
Serving thick star-shaped slices
Thick slices are crisp, slippery and the wrong shape for a small airway. Cook spears soft for babies, and cut thin slices into small pieces for toddlers.
Serving it raw and crisp to a baby
Hard raw fruit is a choking hazard for babies. Cook star fruit until it squashes easily.
Missing seeds
Star fruit has a few flat seeds near the middle. Pick them all out.
Giving star fruit juice or lots of the fruit
Star fruit contains oxalate and a natural toxin, caramboxin. Medical reviews describe kidney and nerve problems mostly in people with kidney disease, and also in some people with previously normal kidneys. Reported cases include concentrated juice and eating it on an empty stomach. Offer a small portion with other food, and no juice.
Where US and UK guidance differ on star fruit
United States(AAP and CDC)Your setting
For babies under 1, the AAP says that apart from mashed banana, most fruits should be cooked until soft, and it lists fruit chunks among foods to avoid under 1. Soft-cooked or mashed star fruit follows this advice. After 12 months, the CDC lists pieces of hard raw fruit as a choking hazard, and the AAP advises holding back raw fruit chunks until about 4 years, depending on the child. If you follow US advice, keep cooking star fruit soft.
United Kingdom(NHS)Your setting
The NHS lists slices of soft fruit as finger foods from around 6 months, and suggests cooking harder fruits. Raw star fruit is crisp, so cook it until soft for babies, and always remove the seeds. From 12 months, the NHS snack list includes raw fruit such as slices of apple, so very thin raw slices cut small fit UK advice. Stay with your child while they eat.

Questions parents ask
Can star fruit be a choking hazard for babies?
Raw star fruit is crisp and slippery, the star-shaped slices are an awkward shape, and it has small seeds. The CDC lists pieces of hard raw fruit as a choking hazard for young children and says to avoid small, hard foods, and the NHS says to remove hard pips from fruit. Cook it soft for babies, cut thin slices into small pieces for toddlers, remove the seeds, and stay with your child during meals.
Can babies be allergic to star fruit?
Star fruit is not a common allergen.
Is star fruit healthy for babies?
A source of vitamin C (about 34 mg per 100 g), with a little fiber (about 2.8 g per 100 g). Vitamin C helps the body absorb the iron in plant foods, such as beans, lentils and iron-fortified cereal.
Is star fruit safe for babies?
No AAP, CDC or NHS page covers star fruit for babies, and the medical papers we found describe adults, not children. Star fruit contains oxalate and a natural toxin called caramboxin. Medical reviews describe kidney and nerve problems after eating it, mostly in people who already had kidney disease (94 of 136 people in one review), and also in some people with previously normal kidneys. Reported cases include concentrated juice and eating it on an empty stomach or while dehydrated. So never offer star fruit to a child with kidney problems, skip it while your child is dehydrated or has vomiting or diarrhea, and offer only a small portion with other food, not on an empty stomach. Skip the juice.
Can babies drink star fruit juice?
No. The AAP says babies under 1 shouldn't have juice, and the NHS advises avoiding fruit juice for children aged 4 and under. Concentrated star fruit juice has also been linked to kidney problems in adults with healthy kidneys. Offer small pieces of the fruit instead.
Can babies eat star fruit skin?
Peel it for babies if you can, and always trim off the dark edge of each ridge. The NHS says removing the skin makes fruit easier to swallow, especially for very young children.
If your baby refuses star fruit
- Many babies need 10 or more tries before they accept a new food. Keep offering it alongside foods they already like.
- Star fruit can be sour. Try soft-cooked pieces next to a sweeter fruit your baby already likes.
- Eat some yourself at the same meal. Babies copy what they see.
- Funny faces don't mean they dislike it. They're getting used to a new taste and texture.
Never force or pressure your baby to eat. Some days they'll eat more, some days less, and that's normal.
Buying and storing star fruit
- Ripen green star fruit at room temperature. Once ripe, keep it in the fridge, at 40°F (4°C) or below.
- Cooked or cut star fruit keeps for 3 to 4 days in a covered container in the fridge.
- Throw away any food left out at room temperature for more than 2 hours (1 hour if it's hotter than 90°F / 32°C).
When to talk to your doctor
Contact your pediatrician, GP or health visitor if:
- Your child has kidney disease or any kidney problem. Don't offer star fruit: medical reviews say people with kidney disease are most at risk of star fruit poisoning, and people with undiagnosed kidney problems could also be at risk. Ask their doctor if you're unsure.
- Your child vomits or has hiccups that won't stop after eating star fruit. Call your pediatrician the same day and tell them about the star fruit. If they have a seizure, are confused, or are hard to wake, call your emergency number instead (see below).
- You notice mild signs of an allergic reaction after eating, such as a few hives or a little vomiting. See signs of a reaction.
- You're worried about how much your baby eats, their growth, or they refuse most solid food for weeks.
Call 911999your local emergency number (such as 112 in Europe or 000 in Australia) now if your baby has trouble breathing, wheezing, can't cough or cry, has lips, mouth, tongue or throat that suddenly swell, or becomes pale, bluish, floppy or unresponsive. Also call if hives come with repeated vomiting.
