Children love to eat French fries. Teach your baby the sign for the word French fry in baby sign language with the following description and video.
Form the signed letter F of the sign language alphabet. Bounce the hand in front of the center of the body. Then bounce the hand to the side in the motion of dipping a French fry in ketchup.
