Hello Child is one month and one year old today. He has green phlegm and can't clear his nose with a suction bulb. I tried using a suction bulb but he cried so much after that. It took me exactly 30 minutes to calm him down. And he even got upset with me. ? Now the question: How do you get him to clear his nose? He can't even breathe properly.
