How do I treat a cough and chest congestion for a 5 month old infant? Should the baby be taken in to see a physician?

Cool mist humidifier. If he has a fever, poor appetite then yes see a dr because he is so young.
Unfortunately. Unfortunately there are no over the counter medications that treat cough and chest congestion in a 5 month old. For this reason it is important to bring the baby in for an evaluation of their symptoms. Prescription medications can be prescribed as deemed necessary. A few things you can do for babies this age is to put a humidifier or cool mist vaporizer where the baby sleeps, use pediatric salt drops (peds ocean spray) for nasal congestion, and tylenol (acetaminophen) as needed for fever, pain, and irritability (indicator of pain). All the best.

My infant has chest congestion I was told by a doctor to use a bulb syringe and saline, but nothing comes our her nose, am I doing something wrong?

Just watch. Nasal bulb suction is not really of help for chest congestion. Watch for heavy breathing, fever, and feeding difficulties which require medical attention.
Bulb not for chest. Use a cool mist humidifier. Keep head end elevated. No smoking around him at all.
? age? The first months are troubled by narrow nasal passages & exposure to dust, fragrences, smoke & other irritants. Baby tries to flush these out of the nose with mucous but this often ends as congestion & produces rattling with breathing. The best rx is washing out the nose with copious amounts of saline & suctioning the remainder. Eliminate irritants from babies environment & this will happen less.

Nothing wrong! You are doing nothing wrong. Bulb syringe will help with nasal congestion and mucous. Chest congestion may be helped by humifier. If labored breathing or persistent fever, get your infant seen by an experienced Pediatrician!
