The potato sign is like sticking a fork into a potato. To sign potato, make your non-dominant hand into a fist and put it out in front of you. Make your strong hand into a fist with your index and middle fingers extended and bent at the knuckle. Now tap the fingers on top of the fist.
Get together a few fruits and vegetables and play a little game with your baby to identify each item.
Once your baby begins eating solid foods, you will be able to include signs like potato. When we teach food signs, we try to give our baby the opportunity to see the food product raw as well as cooked. You can also consider planting a garden with your toddler as a way for them to learn how things grow.
