To sign bite, you start with your dominant hand, which will represent a mouth biting something. It will bite your non-dominant hand at chest height, with the non-dominant hand in a flat, palm-downward position.
The sign looks like one hand biting the other hand.
You can use bite to teach your child to eat by taking bites, or to correct biting behavior common in toddlers. You can also teach the words food and apple at the same time as bite, to help your child learn what the words mean. You could say something like, "Bite your apple," and, "Don't bite your friend."
Use the bite flash card in conjunction with the food and apple flash cards. The goal is to help your baby make the connection between the action of biting and objects he or she is likely to bite. Also, consider combining the sign with teaching a baby not to bite. As your baby gets more advanced, you can introduce the added challenge of exploring sizes by introducing him or her to signs like small and big, with the idea of teaching your little one about a big bite and small bite. Consider using a banana or apple. You may also wish to introduce baby to a variety of food items on their plate, and ask them if they would like a bite of apple and cheese, and bread or pizza, to help your baby identify and communicate food preferences.
