Eyelashes is a natural sign. To sign eyelashes, take both hands and form them into a modified number 4 sign, with palms facing out. Then hold both hands to your eye level, first facing down, then fanning upward, just as if you are batting your eyelashes.
Teach your baby the eyelashes sign along with the other parts of the body.
This is a useful flash card taught best in conjunction with the other body parts flash cards when your children are ready. It is good to complement the body parts flash cards with nursery rhymes, like "Head, Shoulders, Knees and Toes".
