Hi Alex - apparently his talking switch is not switched on for some reason (but they don't know why not). He is trying to talk but just can't do it - it just sounds like a series of grunts (but I know what he is trying to say). His hearing is fine (been discharged by the hearing people), he has no problems eating or drinking (which if he did could affect his ability to speak). They think by having signs to attach words to it will help him speak.
