Yes, I have. A friend had 2 deaf little girls and 1 hearing son (he was the youngest). She had no speech at all, taught the girls ASL and the little hearing boy knew some ASL also. He very rarely, if ever, "talked"...altho' he could hear.....she did enroll him in daycare with other hearing children, so his speech got better and better. He's a teenager now and is doing fine.
