So my little one is 5 months old. He's been congested for a week now. I took him to the dr last week and she gave me a nebulizer treatment to do twice a week.. that hasn't helped. I've tried saline drops, suctioning his nose, hot misty bathroom, humidifier. It has messed up his sleep schedule and makes him so fussy. I feel so helpless. Any other suggestions? I can hear his mucus stuck in his throat\chest when he breathes. He doesn't have a runny nose or anything
