To sign vegetable, make your dominant hand into a 'V' shape with the middle and index fingers sticking up. Put the index finger to the side of your lip and pivot your 'V' hand at the wrist. The vegetable sign is like the fruit sign, but the latter only uses the index finger.
Sign vegetable as you put a plate of boiled vegetables on your baby's tray.
Teach your baby the vegetable sign in conjunction with the fruit sign and other food varieties that are both healthy and delicious for your growing child. As your child's food signs increase, they will be able to sign what they would want to eat in the future, avoiding unnecessary fussiness.
