Do you have a young child or loved one who is always grabbing for their pacifier or continuously sucking their thumb? During early infancy, and even in the womb, it is natural for a baby to suck their thumb. It is a self-soothing technique and actually helps to teach them about the environment around them. Thumbsucking or pacifier use is also helpful as children transition into the late infancy stage and the early toddler years, as it can also be used as a coping mechanism when a child is feeling anxious or overwhelmed. At a certain age, pacifier use and thumbsucking become problems as it regards their teeth.
