Which behavior might indicate that a 6-month-old infant is teething?

While pulling at their ears can be a common behavior in infants, it is not a specific indicator of teething. The behavior that most commonly indicates that a 6-month-old infant is teething is excessive drooling. During teething, infants often produce more saliva than usual as their gums react to the pressure and irritation caused by emerging teeth. This can lead to noticeable drooling, and caregivers might find themselves frequently wiping the baby’s mouth and chin.

Increased sleeping, while it may seem related, does not typically correlate directly with teething. Some infants may sleep more due to discomfort, but this could also be related to numerous other factors like growth spurts or fatigue. Refusal to eat can sometimes accompany teething due to gum discomfort, but it is not as definitive an indicator as excessive drooling. Therefore, excessive drooling is the most characteristic behavior associated with teething in infants.
