Newborns sneeze frequently to clear their nasal passages of irritants like dust, lint, or mucus. Their narrow nasal passages make them more sensitive to environmental factors. Sneezing is also a natural reflex that helps them adjust to breathing outside the womb. Occasionally, it could indicate a cold or respiratory infection, but if your newborn is otherwise healthy, it's likely nothing to worry about. Ensure a clean environment and proper humidity levels to ease any congestion. Consulting a pediatrician is advisable if sneezing persists or is accompanied by other concerning symptoms.
