It may be challenging to determine if your baby is undergoing the six-month sleep regression or teething, as both may have overlapping symptoms. However, some signs specific to teething that may not manifest during sleep regression include excessive drooling, an urge to chew on things, and swollen or tender gums (9). If you observe these symptoms in your baby, it may indicate they are teething. Speak to your pediatrician to ascertain the cause of sleep disturbance and get the proper guidance to manage your baby’s sleep issues.
