Before Asher got his tonsils out, all the sounds he made were very glottal/throaty sounds. We would plug his nose to show him where the sound needed to come out, but it was really difficult for him because his tonsils were so huge. Now that those nasty tonsils are gone, he's learning he can make sound come out his mouth instead. Only rarely do we need to plug his nose anymore!
Also, we've been trying to get him to open his mouth to make noise instead of just a humming kind of sound. He just figured it out...Like this!
Anyway, Angela has been very interested working as speech therapist for Asher. Cute therapist, cute student!
