My 7 week old almost 8 week old is very congested and has a cough wondering what i can give her for medicine to help. she has no fever&acting normal?

No meds: No medicine is recommended, definitely no cough medications. You can use normal saline drops in the nose and the bulb syringe, also put a humidifier in the room or steam from the bathroom. Frequent and smaller feeds tend to help to keep him feeding well. If he has. Fever >100.4, breathing hard, see a doctor asap.

Humidity: Run the shower and make a warm steamy bathroom and sit with your daughter in it for five or ten minutes. Alternatively you could try some saline drops followed by bulb suction one nostril at a time but babies hate that.
