Question
Why does a 3-month-old baby often smile?
Answer
A baby often smiling at this age can be a normal part of emotional development, but it could also indicate a deficiency in trace elements. It’s recommended to first conduct tests for trace elements. If zinc deficiency is found, consider administering zinc gluconate oral solution. Additionally, it’s important to increase the zinc content in the diet, so it’s suggested to consume foods rich in zinc, such as whole grains, tofu, beef, mutton, fish, lean meat, peanuts, sesame seeds, dairy products, and cocoa. Wishing the baby healthy growth.
