Nanny is a complex sign, combining the signs for care and person. To make the care sign first, form two letter 'K's with both hands, one on top of the other, and make little circles toward the center of your body. Then to sign person, stretch your hands in front of you and move them in a downward direction, shaping the silhouette of a body.
This sign is best learned contextually if your child has a babysitter, nanny or caregiver.
Nannies can be a big part of our lives. Teach your baby how to sign nanny as part of their basic signs, particularly if they attend day care.
