Question
At around 40 days old, the baby makes a sniffling sound while breastfeeding. Is it due to excess mucus or a condition?
Answer
The sniffling sound the baby makes while breastfeeding at around 40 days old could be caused by excess mucus or underdeveloped laryngeal cartilage. If there is no sign of a cold, consider using a five-dimensional calcium oral liquid or calcium carbonate d3 granules for treatment, and appropriately expose the baby to sunlight to supplement calcium."
