What are people doing with their kids?

When you buy infant sleepwear there is usually a bright yellow tag on it that says: "FOR CHILD’S SAFETY, GARMENT SHOULD FIT SNUGLY. THIS GARMENT IS NOT FLAME RESISTANT. LOOSE-FITTING GARMENT IS MORE LIKELY TO CATCH FIRE." I want to know what people are doing with their kids at night that the babies are catching fire! I don't know about other people but we are not putting Libby to bed over a campfire to keep her warm or anything. Are babies getting so hot at night that they are spontaneously combusting? These are things I think about in depth... Do I have too much time on my hands??
