Liam absolutely loves to 'talk' on the phone. He even goes so far as to stare at the phone and grin at it when I am using it. He's been doing a good job keeping in touch with the family while we've been away. He will laugh, smile and grunt as he listens to Daddy, Mimi or his siblings when they talk to him.
Apparently he loves the phone so much that he will even think it's great to 'talk' to the automated recording.
