3 months, stuffy nose for a long time, it has never been better

Patient's question:

Nasal congestion onset time: 5 months, has already started testing Examination results: None Previous treatment history and effectiveness: None What kind of assistance is needed: I don't know if you have any good methods, please help

Doctor's answer:

Always maintain a 45° incline while lying down and elevate the head and face. For unilateral nasal congestion, adopt a side-lying position. Promptly and thoroughly clear nasal secretions to ensure continuous breathing.
Advice: The most direct method for a baby's nasal congestion is to drip a drop of breast milk into their nose, allowing it to moisten the nasal passages.
Nursing care: The weather is quite dry now, and the baby may also be dehydrated. You should frequently offer them a little boiled water to help digest moisture in their body and alleviate dehydration symptoms.
