Pacifier Use: Weighing the Pros & Cons

Infant Sleep · Sleep Safety · Toddler Sleep

There are several factors to consider as you determine if using a pacifier is the right option for your child.

Sleep props are, by definition, any external aides a child requires to fall asleep or stay asleep.  Therefore, if offered to your baby or toddler at nap time and bedtime, pacifiers are sleep props. While we all may know some little ones that have slept well with a pacifier, we also know many who struggle significantly with sleep – due to the use of any sleep prop.  

Allow me to let you in on a little spoiler alert… Pacifiers affect more than just sleep!  Let’s take a look at both a few concerns associated with pacifier usage and some benefits of pacifiers.  Knowing the facts can help you make an informed decision that’s right for your family.

The “Cons” Regarding Pacifiers

• Pacifiers keep sleepers in a lighter stage of sleep.  Thus, pacifier usage for prolonged periods of time in older babies can impact your child’s quality of sleep.  A child sleeping with a pacifier achieves fewer hours of the deepest levels of the most restorative REM sleep when compared to those who are pacifier-free.  If your child is having trouble consolidating sleeping hours overnight after the newborn phase, it may be caused by pacifier use.

• Until children learn to re-insert pacifiers independently as older infants, the “Paci Pong Game” can exhaust an entire family.  Especially after the change in sleep that occurs around four months of age, some parents will be woken after nearly every one of their little one’s sleep cycles solely to reinsert a pacifier.  This, of course, negatively impacts sleep for the whole household.  

• The use of a pacifier can impact a child’s ability to soothe himself through various experiences during the day.  If a baby is accustomed to always using a pacifier to soothe through boredom, teething, etc., overall fussiness can increase. Regulating emotions independently is a great skill for little ones to practice as they grow.

• In general, it is fair to say we see more sleep disturbances in infants and toddlers using pacifiers.  That is – at least in part – due to the fact that pacifiers are famous for drowsiness.  When a child uses a pacifier during awake times, it often falsely restores sleep pressure.  This can result in short naps, early morning wakings, and overnight wakings. While these sleep issues are very common, they tend to be more prevalent with the reliance on a sleep prop like a pacifier.  

Potential Medical Concerns Associated with Pacifiers

• A pacifier can act like a splint, keeping an airway open for nasal breathing.  Unfortunately, this can mask red flags for sleep-disordered breathing.  In my line of work, I prefer to teach little ones to maintain open airways without something in their mouths.  If a parent has concerns about a child’s risks for obstructive sleep-disordered breathing, I recommend seeking an evaluation.  In such cases, input from a feeding therapist or SLP who focuses in airway health is helpful.

• The most natural resting position for the tongue is sealed to the roof of the mouth. Using a pacifier prevents that position, which over time, can lead to mouth breathing.  This occurs because the muscles in the lips aren’t built adequately enough to keep the lips sealed at rest.  Mouth breathing often contributes to narrow palates, teeth crowding, and other potential dental or health risks down the road.

• Depending on the frequency and duration of the pacifier use, your baby can develop a tongue thrust. This is a concern because thrusts can cause a dysfunctional swallowing pattern and a host of dental issues.  Unfortunately, there are other complications that can arise as well, including middle ear drainage issues, low tongue posture, chronic nasal congestion, and enlarged tonsils/adenoids.

• Toddlers that use pacifiers for daily awake times can impact language development.  Young children are less likely to explore different sounds with a pacifier in their mouths while they are awake.  At times, delayed speech is a consequence of continuous pacifier usage.

The “Pros” of Pacifiers

Of course, there are some benefits to using pacifiers, too!  

• Many newborns naturally prefer to suck to soothe, which is age-appropriate.  A pacifier can be especially helpful in the first couple months of a baby’s life.  It is not wrong to use a pacifier to calm or soothe your baby, especially in the early weeks.  

• Some parents feel that dropping a pacifier is ultimately easier than ending finger or thumb-sucking. Though the impacts on sleep are not the same, the ability to fully remove a pacifier from the sleep environment can be helpful in the weaning process.

• A pacifier offers temporary distraction and more immediate soothing in times of discomfort.  A few circumstances in which keeping a pacifier handy can be of help to your child: 
-taking off or landing on an airplane
-following immunizations, procedures, or blood tests

Potential Medical Benefits Associated with Pacifiers

The AAP recommends using a pacifier during the first six months of life as a protective measure against SIDS. To be clear, protective does not equate to preventative.  Thus, it is crucial to understand that not using a pacifier does not increase the likelihood of a SIDS event.  This can be confusing to parents, as undoubtedly, we all want to do is the best for our children.

• Using a cylindrical shaped pacifier, such as an Avent Soothie, can be helpful for suck training.  With this pacifier, your baby can lift the sides of the tongue to wrap around the nipple, just as he or she does when nursing.

• At birth, babies’ lower jaws are naturally recessed due to the birthing process.  Using a pacifier with a flat base can help bring the lower jaw forward, opening the airway.  I always recommend reaching out to a lactation consultant before doing so to avoid nipple confusion.

So What Does This Mean for my Sleeper?

All humans cycle into lighter stages of sleep about three to five times throughout the night. That means, when a baby requires a pacifier to fall asleep, he or she will wake up looking for the pacifier to be replaced through these sleep cycle transitions. What we desire for our children is that they can rise to the surface of sleep, reposition, get comfortable again, and confidently go right back to sleep on their own without requiring intervention. This helps our little ones get the best sleep possible.

When choosing to teach your baby or toddler how to fall asleep independently, we only want to have to begin this process once!  We strive to avoid the need to re-teach self-soothing skills later when an additional sleep prop, like the pacifier, needs to be removed.  Ideally, our team typically recommends embracing prop-free sleep by 12 weeks of age to enjoy the long-term benefits of healthy sleep habits.  This ensures little ones truly learn the skill of independent sleep, long before the changes associated with the four-month sleep regression (which is not inevitable!) occur.

After weighing the pros and cons, each family can determine if a pacifier is worthwhile.  Regardless, you don’t have to do this alone.  If you are ready for a sleep transformation, we can help you embrace changes without looking back!
