Question
Why does a one-month-old baby suck on their fingers?
Answer
Sucking on fingers is a normal behavior in infants under one year of age. It is an important way for them to recognize and explore the world. Typically, at this age, babies begin to develop hand-eye coordination and show interest in their own body parts. Parents should not worry unless the baby’s hands are not clean. Otherwise, the act of sucking on fingers itself is harmless. It is recommended that parents keep the baby’s hands clean, allowing them to freely explore and learn.
