We hate to see our children suffer — even from something as simple as a cold. Some parents, however, spend their days watching their children battle life-threatening illnesses. It is a stressful and sad time, but thankfully there are people who do what they can to bring a little cheer into these families' lives. From the Make-A-Wish Foundation to A-listers like Beyoncé and Ellen DeGeneres [1], many out there make it their mission to put a smile on a sick child's face — and bring a tear to our eyes. We dare you not to cry while watching these children's dreams come true.
