When can babies have citrus?

Citrus itself is fine from around 6 months, once your baby is starting solids: a little juice squeezed into food, or a large orange wedge to suck on. Segments are the part that waits, until around 9 months, with the membrane stripped and the soft flesh cut small, as our orange page shows. The idea that citrus must wait until after the first birthday is a myth. It is acidic, which is worth knowing about, but it is not dangerous.

🍊 From about 6 months as juice in food or a large wedge to suck. Segment pieces, membrane off and cut small, from about 9 months. Not a top allergen. Always remove the seeds.

Acidity, not allergy

Citrus is acidic, and in some babies that acidity causes a mild red rash around the mouth or a touch of diaper rash a bit later. Both are usually harmless irritation, not an allergic reaction. If you cannot tell irritation from a rash or hives, treat it as a reaction and follow the steps below. If your baby seems bothered by the acid, offer citrus a little less often and alongside other foods.

A genuine citrus allergy is uncommon, but know the signs. Call 911 (or your local emergency number) right away if any of these show up soon after a food, on their own or together: swelling of the lips, face, eyes, or tongue; swelling or tightness in the throat, or trouble swallowing; vomiting; hives that spread beyond the mouth and face; trouble breathing, noisy breathing, or wheezing; a cough that keeps going; a hoarse voice; skin or lips that turn pale or blue; or a baby who goes floppy or limp, or is suddenly sleepy or hard to wake. If the only sign is a new rash or a few hives around the mouth or face, stop the food, watch your baby closely, and call your pediatrician. If anything else about your baby worries you, call 911.

How to serve citrus safely

Worth it for the vitamin C

Citrus is rich in vitamin C, which helps the body absorb iron from other foods. Offering a little orange alongside an iron-rich meal is a smart pairing during the first year, when babies need plenty of iron.

Citrus fruits to explore

Sweeter and easier to start with: orange, clementine, and pomelo. More tart, so cook them into food or offer a small taste: grapefruit, lemon, lime, and kumquat. Lemon and lime are a squeeze in food, not a wedge to suck.

Frequently asked questions

When can babies have citrus?

Citrus itself is fine from around 6 months, when your baby starts solids: squeeze a little juice into their food, or offer a large orange wedge to hold and suck, with the seeds and tough membrane removed. Segments wait until around 9 months: strip off the membrane, remove every seed, and cut the soft flesh into small pieces. Citrus is not a top allergen, so there is no allergy reason to delay it.

Is citrus too acidic for babies?

Citrus is acidic and can cause a harmless red rash around the mouth or a bit of diaper rash, but it is not harmful and does not need to wait. If you cannot tell irritation from a new rash or a few hives around the mouth or face, treat it as a mild sign: stop the food, watch your baby closely, and call your pediatrician. If your baby seems uncomfortable with very acidic fruits, you can simply offer them less often and pair them with other foods.

Does citrus cause allergies in babies?

True citrus allergy is uncommon. The redness some babies get around the mouth is usually skin irritation from the acidity, not an allergic reaction. Call 911 (or your local emergency number) right away if any of these show up soon after a food, on their own or together: swelling of the lips, face, eyes, or tongue; swelling or tightness in the throat, or trouble swallowing; vomiting; hives that spread beyond the mouth and face; trouble breathing, noisy breathing, or wheezing; a cough that keeps going; a hoarse voice; skin or lips that turn pale or blue; or a baby who goes floppy or limp, or is suddenly sleepy or hard to wake. If the only sign is a new rash or a few hives around the mouth or face, stop the food, watch your baby closely, and call your pediatrician. If anything else about your baby worries you, call 911.

How do I serve oranges to a baby?

From around 6 months, squeeze a little juice into food, or offer a large wedge to hold and suck, with the seeds and tough membrane removed. From around 9 months, peel the fruit, remove all seeds, strip the tough membrane off each segment, and cut the soft flesh into small pieces. Never hand over a whole segment: it is firm, round, and wrapped in a chewy membrane, a classic choking shape.
