Thumb-Sucking Versus Pacifier Use

Topic Overview

Many parents of a thumb-sucking infant question whether they should substitute a pacifier for the thumb. So far, research does not show that one is preferable over the other. Also, although parents can encourage a child to suck a pacifier rather than a thumb, they can't control which the child will prefer.

The advantages and disadvantages of pacifier use and thumb-sucking aren't always entirely clear. So there are some general issues for parents to think about.

The advantages of using a pacifier include being able to control when your child is allowed to use it and being able to take the pacifier away when it is no longer appropriate. But a young child who uses a pacifier may be more likely to get ear infections.

An advantage of thumb-sucking is that it may not interfere with breastfeeding. And children usually stop on their own between the ages of 3 to 5. But if thumb-sucking is a habit past age 4, the child may develop dental problems. Also, it may be more difficult for a child to stop thumb-sucking than using a pacifier.

Talk to your doctor about how long you should wait before you introduce a pacifier to a breastfeeding infant.

Keep in mind that there is no reason to encourage thumb-sucking or pacifier use in infants who do not show a need. The sucking instinct in these infants is satisfied through breast- or bottle-feeding.
