In times of stress, people have many ways to comfort themselves. For adults, it can be habits such as eating, drinking, or smoking. For children, it is often sucking their thumb, fingers, or a pacifier. Babies have been observed in scans to suck on their fingers and thumbs even before they are born. It makes them feel secure.
Sucking on fingers or thumbs can be a problem when it is done too vigorously and too long. A young child's jaws are soft and can change their shape to make room for the thumb if the child sucks too hard and too often.

If thumb, finger or pacifier habits continue too long, the upper front teeth may tip toward the lip or not come into the correct position in the mouth. Thumb-sucking can be a hot button issue in many homes that have young children.
Some parents feel stressed, wondering how they can help their child break this habit as soon as possible, while others feel the action is a soothing one that shouldn’t be banished right away. Most children naturally stop sucking their thumbs, fingers, or pacifiers between the ages of two and four.
Pacifier habit is easier to solve than the habit of thumb or finger sucking, perhaps because it is always easier to find them a finger or thumb. It is a good idea to try to transfer your child's pacifier habit at an early age.
