Has your LO been having stuffy nose? With the recent cold weather at night, my LO always has trouble sleeping and would really make a fuss through the night when he is uncomfortable. This nasal spray worked very well for me, 1-2 sprays later he stops crying and can sleep for few more hours. https://www.samplestore.com/products/xepa-soul-serenaz-natural-sea-water-nasal-spray-pediatric
