My DS is 16 months and has had a stuffy nose when he lies down and only when he lies down. We tried saline and suctioning him every night before bed, baby vicks on his chest and feet, humidifier (NY is SUPER humid now it's hot), propping him up while sleeping on a beanbag (he rolls himself off), lil'noses for a few days which helped a tiny bit but cannot be used for more than three days, I can't think of anything else to do. He sleeps terribly and we with him. DH and I are both already sleep deprived due to teething sleep disturbances and this is making it worse. Any helpful ideas? Anyone gone through this?
