Okay, the full picture of this little boy might be shocking at first glance, so we made it an opt-in image.
It’s not what it appears to be. Redditor nyctibius tells us his little brother tried to make himself a drink in the middle of the night. He dropped and broke (or maybe just spilled) a bottle of rose cordial, which is a syrup you add to milk or water and sugar to make a drink. The syrup is fairly thick and very red. No doubt the boy's wails of failure summoned nyctibius to the scene of the crime, and of course the first thing he did was take a picture of the carnage. The child is fine. The pajamas are probably not.
