Put this Christmas card on your fridge if you're trying to stick to a diet.

Oh man. As one of five kids, there have been some times I wanted to spit up on one of my siblings' backs, let me tell you. Unfortunately, you can't really get away with this after the age of 23 or so. 

This photo was supposed to be redditor Blood181's adorable family Christmas photo. The blond girl nailed her part. But despite using a special Similac no spit-up formula for which this would make a horrible advertisement, Blood181's baby boy managed to vomit all over his big sister's back.
