Wan Chai Steamed Buns can be eaten by babies aged 4-6 months, depending on their individual condition, and cannot be generalized. Wan Chai steamed buns are baked and processed mainly with milk and flour, and have some nutritional value. In general, babies start teething from 4-6 months. During teething, your baby may experience itchiness or discomfort in the teething area, so you can give your baby a small amount of Wan Chai buns for teething, which is good for stimulating the teething area and promoting tooth growth. However, because they contain sugar or other additives, it is not recommended to give them to babies in large quantities as a complementary food to avoid indigestion or allergies. Therefore, during the addition of complementary foods, parents are advised to add iron-fortified rice flour to their babies, or to focus on pumpkin, yam and other root tubers, and the Wan Chai steamed buns should be consumed in moderation.
