My 5 month old is having a horrible time with a cold currently. He's been progressively producing a large amount of phlegm - now to the point that he's coughing almost continuously and having a hard time eating and sometimes breathing. My spouse and I have tried steaming the bathroom with hot showers, as well as using humidifiers but it's not breaking up the mucus enough for him to effectively cough it up.
Is there a proper way to suction a baby's mouth with a bulb syringe? Everything that I've searched for and read states that a baby can be suctioned via mouth or nose with a bulb syringe but all examples only show descriptions and steps of suctioning the nose, not the mouth.
