Question
Why is a four-month-old baby so adept at eating fingers?
Answer
Hello! It’s normal for a four-month-old baby to suck on their fingers. This signifies a stage in a baby’s intellectual development, as well as the preparation stage for hand-eye coordination and the differentiation of finger functions. This behavior also plays an important role in the baby’s psychological development. However, if this behavior persists for a long time, it may become a bad habit.
