My LO is 12 weeks old today and has suffered with stuffy sinuses since she was about a week old. We have been using saline spray to help her. I was thinking about getting a warm mist humidifier to help her, but hubby isn't keen. He doesn't deal well with humidity and she is the same. She wakes during the night and sounds like Darth Vader, which is (I think) affecting with how much she bf's, thus affecting how long she sleeps. We're about to go into summer. What else can we do for her? We got told that she will grow out of it and her nasal passages will get bigger, but its just bugging me slightly
