Baby sign language is the use of sign language in order to communicate with infants and toddlers. While infants and toddlers have a desire to communicate their needs and wishes, they lack the ability to do so clearly because the production of speech lags behind cognitive ability in the first years of life. Proponents of baby sign language say that this gap between desire to communicate and ability often leads to frustration and tantrums. However, since hand–eye coordination develops sooner than acquisition of verbal skills, infants can learn simple signs for common words such as "eat", "sleep", "more", "hug", "play", "cookie", and "teddy bear" before they are able to produce understandable speech.

“It is a sure sign that a culture has reached a dead end when it is no longer intrigued by its myths.”
—Greil Marcus (b. 1945)
“Theoretically, I grant you, there is no possibility of error in necessary reasoning. But to speak thus “theoretically,” is to use language in a Pickwickian sense. In practice, and in fact, mathematics is not exempt from that liability to error that affects everything that man does.”
—Charles Sanders Peirce (1839–1914)
