Peas is signed by taking your non-dominant hand and holding it out horizontally in front of your body, all fingers wound into a fist except the index finger sticking out like a ledge. Then take your dominant hand, form a hook with your index finger, and run it down from the knuckle of your non-dominant index finger to the tip of this index. It's like you're running your finger across the curvy surface of peas in a pod.
Teach your baby the sign for peas when you serve it up for a snack. This is a good sign to teach along with other food and vegetable flash cards, to widen your child's food repertoire.
Peas is a fun sign to teach your baby vegetables. Who knows? Maybe the joy your baby gleans from knowing the sign of this food item will actually make your child enjoy eating this - and other veggies as well!
