There is no need to stop infants from sucking their fingers; this habit often occurs when they are hungry and at bedtime, and will slowly disappear as they get older. Finger sucking in infants is a normal response to what is known medically as finger sucking, which is the repeated or involuntary act of sucking on the finger. Infant finger sucking may occur especially when the baby is hungry or insecure. Finger sucking can also be a habit when a baby is insecure and can bring comfort and relieve anxiety. Baby finger sucking is also a kind of behavior to explore the world, so parents usually do not need to stop it, but must pay attention to maintain hand hygiene. As long as the baby does not have any other adverse manifestations, there is no need to worry too much, hand eating is a normal manifestation, and you should wash your child’s hands more often.
