3-month-old baby coughing up mucus?

The real reply from the in-app AI advisor

Coughing up mucus in a 3-month-old is usually not alarming. At this age, babies cannot clear mucus effectively yet; when nasal drainage, saliva, or nasal secretions accumulate, they may cough or gag and expel a slimy, sticky liquid. The most common causes are: a mild upper respiratory tract infection, excessive drooling (even early teething symptoms in rare cases), or reflux-related mucus buildup.

If the baby's general condition is good — no fever, breathing easily, feeds normally, alert during the day — gentle nasal cleaning at home (saline rinse + aspirator) and elevating the head slightly are enough.

When to contact your doctor: if the vomitus contains blood or green bile, if the baby wheezes while breathing, if temperature is above 38°C, if feeding is refused, or if there's no wet diaper for 8+ hours — any of these warrants a pediatrician call. Otherwise, observation is sufficient.
