When can babies eat lemon?
Lemon is a flavor, not a food you serve on its own. A whole wedge is mouth-puckeringly sour, so no baby is going to sit and eat one. What lemon does beautifully, from around 6 months, is brighten other foods: a squeeze of juice over fish, a little zest stirred into a puree, a splash into a vegetable mash. It is not a common allergen, so the main thing to know is that its acid can cause a harmless rash.

Is lemon safe? Choking & prep
Lemon is a seasoning, so use small amounts of juice or zest stirred into food rather than serving it plain. The acid in lemon can cause a harmless red rash around the mouth, cheeks, or bottom where the juice touches skin, and this is irritation, not a food allergy. If you see it, it usually fades on its own; wiping your baby's face after eating helps. Very rarely, some people get itching or tingling in the mouth from citrus, called oral allergy syndrome, so watch as with any new food. Do not add salt or sugar.

Lemon brings vitamin C and a bright, sour flavor for very little volume. The vitamin C helps your baby absorb iron from foods served alongside, so a squeeze over lentils or greens does double duty. Its main job is making other nutritious foods more appealing.
