Question
My baby who is 2 years and 10 months old often sucks their fingers. I don’t know what the reason is?
Answer
According to medical observations, a baby may suck their fingers due to a deficiency of trace elements, particularly zinc. It is recommended that parents take their child to the hospital for a test of trace elements. If zinc deficiency is confirmed, you can give your child zinc gluconate oral solution to supplement. In addition, you can increase the intake of zinc-rich foods in their daily diet, such as whole wheat flour, tofu, beef, lamb, fish, lean meat, peanuts, sesame seeds, dairy products, and cocoa. I hope these suggestions will help your child grow up healthily.
