To determine whether your baby’s nasal congestion is a cold or rhinitis, you can observe the duration of the symptoms, the color of the nasal discharge, the frequency of sneezing, and whether there are symptoms such as nasal itching. 1. Observe the duration of symptoms: if it is a common cold, it will get better in 2-3 days after reasonable treatment, and will be cured in 7 days; if it is rhinitis, the symptoms will last more than 10 days or even longer. 2. Observe the color of nasal mucus: If nasal congestion is accompanied by nasal mucus, you can judge by observing the color of the baby’s nasal mucus. Colds are usually clear mucus in the early stage, but it will be changed to mucus mucus or yellow mucus at the later stage; rhinitis is usually clear watery nasal mucus and the amount is large, and the symptoms persist. 3. Observe the frequency of sneezing: colds are usually non-continuous sneezing and less in number; rhinitis is usually continuous sneezing and more in number. 4. Observe whether the baby has an itchy nose: colds generally have fewer symptoms of itchy nose; rhinitis generally has symptoms of itchy nose. Parents who find that their babies have symptoms of nasal congestion should seek medical treatment as soon as possible and under the guidance of the doctor, do not deal with it blindly, so as not to delay the condition or cause adverse consequences.
