For babies, sucking is natural. It’s undeniable that pacifiers can help your baby feel more at ease, especially if she has a strong need to suck but hasn’t yet figured out how to put their fingers in their mouth. Some toddlers suck their thumbs or fingers, while others enjoy sucking on pacifiers. In addition to being a big aid to parents, pacifiers frequently serve as a sort of security or comfort. For many babies, a pacifier turns on the comfort and stops the crying, making it seem magical.
