This momma isn't getting any sleep tonight :/ the past few nights, my daughter has been getting so congested and nothing helps her. I've ran a vaporizer, nose drops, hot showers, suctioning, vapor rub, nothing helps. She can't sleep unless I'm holding her and sometimes not even then. I just don't understand why this only happens at night
