To make the sign for flower, hold your fingers and thumb together, as if you were pinching the stem of a flower, or as if your hand itself were a flower bud. Now move your pinched fingers from one side of your nostril to the other. It is as if you are really immersing yourself in the fragrance of the flower.
Go outside with your baby and pick some wild flowers. Everyone else might think they are weeds, but you know they are for making a fairy crown for your baby. As your baby's interest is captured by the flower, make the sign.
One of our favorite signs is flower. Use the flash card along with real flowers in the garden to teach your baby the sign. You will be surprised at how observant your baby can be after you teach her the sign.
