The sign for "mommy" or "mama" in American Sign Language (ASL) is made by extending and spreading out your fingers on your dominant hand. With your pinkie facing forward, tap your thumb on your chin. The sign for "mom" is similar, but the thumb touches the chin only once. The sign for "mommy" is the same as the sign for "daddy," but signed lower on the face. It is important to note that there are variations of the sign for "mom" or "mother" in ASL, such as wiggling the fingers or using a double tap on the chin.
