This Momma Needs Some Suggestions

Current sitch in our house unfortunately! I'm sure many other households are dealing with the same thing and I feel you, it's not fun. In the last couple of days, I have equipped myself because I have a little 4 year old and an 11 year old who are having trouble sleeping at night, so I need some help from other momma's! 

What are your remedies, homemade or otherwise to help a little one who's up coughing all night? The Vicks vaporruuuuu is by the night stand, cough drops and water bottle. Beyond that and cough medicine any suggestions from other parents?
