How many times can you use the nasal aspirator in a day?

It is safe to use the nasal aspirator as often as needed throughout the day, following the administration of saline drops. In regards to your second question, if your child has had nasal secretions for about ten days without a fever and is otherwise in good health, there may not be a need to worry. A cold typically takes around 5-7 days to clear up, but some symptoms like coughing or nasal secretions can persist for a while longer. If your child is eating well, sleeping well, and is in good spirits, it may not be necessary to consult a doctor at this time.
