Soybean for babies: when and how to serve

Q: When can babies eat Soybean?

For younger babies, serve soy as silken tofu, mashed edamame, or other soft soy foods. For older babies, flatten, mash, or split beans and offer soft tofu in age-appropriate pieces. Avoid whole mature soybeans for young children.

About Soybean

Soybeans are legumes that can be served to babies in several forms, including soft mashed edamame, tofu, and tempeh. They are a versatile plant food and can be a useful part of a baby's diet, especially for families who eat vegetarian or mixed diets. For infants, softer soy foods are usually the easiest and safest way to start. Soy provides protein for growth, iron for developing blood and brain function, folate for cell growth, and fiber for digestion. Depending on the form, soy foods can also contribute calcium, zinc, and healthy fats. Tofu and mashed edamame are especially practical options because they can be prepared in textures that work well for early self-feeding. Soy is a common allergen, so it should be introduced thoughtfully. Reactions can include hives, swelling, vomiting, diarrhea, coughing, or wheezing. Soy can also trigger FPIES in some infants, which may cause delayed repetitive vomiting and lethargy a few hours after eating. Whole soybeans and whole edamame can be a choking risk for babies and young toddlers because they are small, firm, and round. Most babies can start soy from 6 months old in soft forms such as silken tofu, mashed edamame, or soy mixed into other foods. Around 9 months, many babies can manage small pieces of soft tofu or well-mashed soy foods. Whole edamame and whole mature soybeans should be delayed until chewing skills are more reliable, and even then should be served with caution and close supervision.
