Teething diaper rash – Teething and exhaustion are what I call the “catch-alls” of parenting. Is your baby grumpy, fussy, or unusually whiny and clingy?

Then they’re either tired or teething, which is a good bet. Or, at the very least, that’s what we’ll tell ourselves and everyone else, right? However, you may be surprised to learn that many of the symptoms you believe are caused by teething, such as a diaper rash and fever, are not.


What Exactly Is Teething?

First and foremost, what is the teething process for babies? According to the American Academy of Pediatrics (AAP), teething typically begins around 6 months of age for babies and lasts for 30 months. Through the teething process, infants will gain a total of 20 baby teeth.

Because those 30 months are so important for development, the AAP notes that normal growth, passing illnesses, and a still-developing immune system can all cause many of the symptoms we associate with teething. In other words, don’t assume your child’s diaper rash is caused by teething.



What Are the Symptoms of Teething?

Most of us are familiar with the traditional symptoms of teething — or believe we are. Teething was always the cause of my children’s unusual nighttime awakenings, extra clinginess during the day and night, fussiness, and rosy cheeks.


But, to be honest, I was never really that attentive to the precise moment a tooth would pop through. Let’s face it, a baby has a lot of teeth, and it can be difficult to determine whether any strange symptoms are due to teething or something else.


In one study, 475 tooth eruptions in a group of children were examined. They discovered that there is a “teething window” in children that is accompanied by some predictable signs and symptoms. The study discovered that symptoms generally occurred four days before the teeth came through, the day the tooth actually popped through, and three days afterwards, for a total of eight days.


Surprisingly, they discovered that while many symptoms commonly associated with teething did occur, many other symptoms were not.


Teething caused the following symptoms:


heightened biting







Rash on the face

reduced desire for solid foods

mild temperature rise (less than 102 F)

The following symptoms did not occur as a result of teething:



sleep disruption

a greater number of bowel movements

increased frequency of bowel movements

decreased thirst for liquids


rashes that are not facial rashes

Fever of more than 102°F


Another study discovered that parents frequently exaggerate their babies’ teething symptoms. Could it be that because you believe your child is teething, you’re looking for symptoms that don’t exist? I’m not sure, but I’ve had some pretty cranky kids who magically transformed into happy, smiling babies once that fateful tooth popped through.


So, what does it all mean? It’s bad news if you’re hoping that your baby’s diaper rash will simply disappear as a result of teething, because studies show that diaper rash is not a symptom of teething. The following are some of the most common causes of diaper rash:


diarrhea or watery stools

sensitivity to urine, stool, or new products

diaper changes are infrequent

Infection with yeast

dietary modifications

Loose stools or diarrhea in babies can be caused by a variety of factors, including diet — particularly excess sugars — viral or bacterial infections, antibiotic use, and, in rare cases, intestinal or digestive disorders. If your child has diarrhea or loose stools, keep an eye on them and use a baby-safe diaper rash cream with each change to prevent the diaper rash from worsening. Allow those baby buns to air out as well. To keep mishaps at bay, we like to let baby explore on a towel or old blanket.


The Bottom Line

While there are many common symptoms associated with the eruption of those infamous baby teeth, parents should not be too quick to attribute all of the symptoms to teething.


Fevers above 102 F, for example, are unlikely to be caused by “just” teething, and a diaper rash is also not a “normal” sign of teething. Many symptoms commonly associated with teething, such as diaper rashes or diarrhea, can have a variety of other causes, and parents should closely monitor those symptoms and seek medical attention if they worsen or do not improve after a day or two.
