finally my son has startedto click on makton signing , we been trying for 18months now and seemed getting nowhere hes 3 1/2with gdd but no speech but yesterdy i signed drink and he signed it back then later signed back more and eat, ok they were clumsy but were there then later on in day without prompting he signed drink was so happy i bust into tears which really confused him.but what I want to say apart from yelling hes doing it from rooftops is that even when we thnk there not going do something they still suprise us
