The lead-up to Christmas is a stressful affair. Yet, no matter how flustered you might feel after excessive gift wrapping, constant Elf-moving and elaborate meal prepping, Christmas morning with little kids is a balm for the grinchiest of grinchy souls. For example, here's young Reese who was so happy while opening his presents, he actually cried. Seriously, this might be the only time when we can say a child making tantrum-face made us feel warm and fuzzy.

We're collecting more evidence of what makes Christmas morning awesome from you. Check out these photos of great reactions from HPP readers' kids -- and add your own best shots to the slideshow.
