Newborns often sneeze, a common occurrence that can surprise new parents. This reflex helps infants clear their tiny nasal passages. Understanding why newborns sneeze can alleviate concerns, as it is often a normal part of their development.
Understanding Newborn Sneezing
Newborns sneeze for various reasons, primarily to keep their airways clear. Since infants breathe almost entirely through their noses and cannot blow them, sneezing is their primary method for expelling irritants. Their small nasal passages are easily affected by tiny particles. This reflex helps prevent substances like dust, lint, dried mucus, breast milk, or formula from interfering with breathing.
Another reason for sneezing relates to environmental adjustments. Newborns are adapting to life outside the womb, and their bodies regulate processes like temperature. Sneezing can also help regulate their body temperature. Changes in light can also trigger this response, known as the photic sneeze reflex.
Sometimes, a sneeze is simply a developmental reflex as the baby’s nervous system matures. This indicates developing senses and functioning protective mechanisms. Occasional, even frequent, sneezing without other symptoms, is part of healthy development.
When to Consult a Doctor
While newborn sneezing is often normal, certain accompanying symptoms warrant medical attention. If sneezing occurs alongside a fever, especially in babies under three months old with a temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher, contact a doctor immediately. Persistent coughing or signs of difficulty breathing, such as flaring nostrils, retractions (when the skin pulls in around the ribs or neck with each breath), or rapid breathing, are also red flags.
Other indicators that a sneeze might be part of a broader issue include poor feeding, such as not waking to feed or struggling to nurse or take a bottle. Lethargy, a significant decrease in activity, or any noticeable change in the baby’s usual behavior also suggest medical evaluation. If sneezing becomes increasingly frequent over a short period, for example, from a few sneezes an hour to many more, especially with other symptoms, it could signal an underlying condition.
Supporting Your Sneezing Newborn
Parents can support a sneezing newborn by maintaining a clean environment. Reducing exposure to common irritants like dust, pet dander, tobacco smoke, and strong perfumes can minimize triggers for sneezing. Ensuring good air quality in the home by using a humidifier can also help, especially if dry air irritates tiny nasal passages.
Gentle nasal care can help if there is visible congestion accompanying the sneezing. Using a bulb syringe or saline drops can help clear mucus from the nostrils, but use these only when necessary and with guidance. For frequent, isolated sneezing without other symptoms, intervention is not required, as it is a natural and healthy bodily function.
