Babies who are not allergic to egg yolks can usually start eating egg yolks at 7 to 9 months. Babies usually start to add complementary foods after 6 months, and babies can try to eat egg yolks after 7 to 9 months because egg yolks contain many protein components, which are more difficult to be digested and absorbed by babies’ intestines younger than 7 to 9 months. If you give your baby egg yolks too early, it can easily lead to constipation, bloating and other symptoms. You need to pay attention to the amount of egg yolk in the food. Start eating a quarter of the egg yolk, when the baby’s digestion and absorption ability has improved to a certain extent, it can be increased to half, and gradually increased to the whole egg yolk. Also take care to polish it finely to aid digestion, which will help your baby get the necessary iron. If your baby is allergic to egg yolk, it is not recommended. If there is any discomfort, prompt medical attention is recommended.
