To sign peanut butter, place the thumb of your dominant hand in front of your mouth, and pull it out and down (which is actually the sign for peanut). Follow this motion with the sign for butter, which is a spreading motion over your non-dominant hand using your middle and index fingers.
We use peanut butter when our toddlers are starting to taste a variety of foods. Practice this sign during snack time.
Food signs are really fun to use when we begin to explore and identify preferences and dislikes. Peanut butter is a family favorite. Practice it during snack time.
