When can babies have fennel seed?

Fennel seeds are sweet and anise-flavored, from the same plant family as the fennel bulb vegetable. They are a classic in Italian cooking and Indian tempering alike.

How to use fennel seed in baby food

Crush or grind firstWhole seeds are small and hard, so crush or grind them before adding to baby food to release their sweet, licorice flavor.

Stir into Italian dishesFennel seed is classic in Italian sausage and tomato sauce, where it adds a gentle sweetness.

Pair with fruitIts aromatic side works beautifully with tomato and with apple, whether in a sauce or a warm compote.

Is fennel seed safe for babies?

Fennel seeds are safe from around 6 months in cooking amounts. Because the whole seeds are small and hard, always crush or grind them before serving to a baby rather than leaving them whole. They come from the same plant family as the fennel bulb vegetable, though the seeds and the bulb are used differently in the kitchen. Skip added salt and sugar for babies under 1, and simply stir the crushed seeds into food for a sweet, aromatic lift.
