Young parents are an interesting breed. Especially young, urban parents. They make their own baby food, they have organic cloth diapers, they're comfortable discussing bowel movements (both the child's and their own) in large groups of strangers.
Young, urban, *tech-savvy* parents are able to make you uncomfortable even when you're not around them. It's an amazing skill. Suddenly your Facebook is inundated with photos of squishy babies (100s of them!) and "adorable" vomit photos.
So, there is a site dedicated to such disturbing photos: STFU Parents. Genius.
Prime example: poop skating.
