"Da Da" has to be the single most beautiful word a child can utter to their father. Whether it is their first word or only word. Brooklyn said "Da Da" today and has uttered it a few times actually over the last week. I know most moms would prefer to hear momma and believe me as a mom I would LOVE it more than anything in this world but as a Rett mom "Da Da" is music to my ears too. As I sit hear hoping that one day I will hear "momma" again I smile, filled with joy, at the precious sound of her little voice saying "Da Da."
