Doctor's answer:

A 5-month-old baby can start eating solid food. For example, you can try adding rice cereal and a small amount of scrambled egg yolk.
You can start adding rice cereal to your child's diet, beginning with 2 tablespoons and gradually increasing the amount. The same applies to scrambled egg yolk.
