When can babies have soybeans?
Can babies have soybeans?
Babies can have soybeans from about 6 months when they are cooked until soft and blended smooth, then mashed from 7–8 months and flattened later. Whole soybeans and edamame are firm and round, which makes them a choking hazard. Soy is one of the Top 9 allergens, so introduce it early in a small amount.
How to serve soybeans by age
Shapes and textures change as your baby’s grasp and chewing grow.
6 months
Cook soybeans or shelled edamame until very soft, then blend them with a little olive oil and water, breast milk or formula into a smooth puree. Offer it on a spoon, or blend silken tofu smooth as another easy way to introduce soy.
7–8 months
Fork-mash soft-cooked soybeans or edamame into a thicker, lumpier mash, or spread the mash on soft toast strips. Strips of soft tofu that squash easily are another good option at this age.
9–12 months
Smash each cooked soybean or edamame bean flat between your fingers before serving, so your baby can pick them up with a pincer grasp. You can also mix mashed soybeans into rice or eggs.
12 months +
Toddlers can have flattened or halved soybeans in stir-fries, salads and grain bowls. Keep smashing or halving them until about age 4, and never offer edamame in the pod.
Why it’s good
Soybeans are a complete protein and give babies iron, zinc, folate, calcium, fiber and healthy fats. They are one of the most nutrient-rich plant proteins. Pair soybeans with a vitamin C food like tomato or bell pepper to boost iron absorption.
Safety notes
- Whole soybeans and edamame are firm and the right size to block a small airway. Mash or flatten them for babies and toddlers.
- Never give edamame in the pod. The pods are tough and fibrous.
- Cook dried soybeans fully. Raw or undercooked soybeans are hard to digest and contain compounds that can upset the stomach.
- Choose plain soybeans and edamame without added salt, and rinse canned soybeans.
- Soy is a top allergen, so offer the first tastes at home when you can watch your baby.
Introduce soybean on its own, then keep it in
Soy is one of the Top 9 allergens. Introduce soybeans in a small amount and watch for hives, vomiting, swelling, coughing or wheezing. Soy allergy is common in babies and many children outgrow it, and once soy is tolerated, keep offering it regularly.
