To do the baby sign for yard, we either finger-spell, or do the compound sign for park, which is grass, and area combined.
To sign grass, hold your open hand under your chin, with palm facing up and fingers spread out and curved. To sign area, take your dominant hand, with fingers spread out and palm facing down, then make a counter-clockwise circle in front of your body.
We mainly use yard to engage our babies in outdoor activities and help them identify areas of the house.
Use the yard flash card in conjunction with the bee, grass, and other related signs.
