Not every night waking during the teething months is caused by teething. Before automatically reaching for the teething explanation, consider these other common causes:
Illness. A baby with a cold, ear infection, or stomach bug will also wake at night — and these are more common than teething during this age range. Check for fever, congestion, or other signs of illness.
Sleep regression. The 4-month, 6-month, 8-10-month, and 12-month sleep regressions all overlap with active teething periods. Regressions last longer (2-6 weeks) and do not respond to pain relief. See our sleep regression timeline for details.
Hunger. Growth spurts increase caloric needs and can cause genuine hunger-related night waking. If your baby eats eagerly when offered a feed, hunger may be the cause.
Schedule issues. A baby who is undertired or overtired at bedtime may wake more at night. If nap times or wake windows are off, sleep quality suffers regardless of teething.
Habit. A baby who was soothed with extra feeds or co-sleeping during a teething episode may continue waking for that intervention after the teething is resolved. The tooth is through, but the habit remains.
