Henry 'talking'

I have been working so hard on Henry's "Learning to Listen" sounds - sounds which represent the different types of speech sounds that babies need to detect, identify and eventually produce as speech.  We have been working on associating different sounds with different toys or actions.  Henry takes after his father, so loves cars or anything with wheels.  So the 'vrrmmm' sound that we always try to associate with these have been heard by Henry over and over again. 
And now he has starting imitating the sound himself!!!!!!  It is so exciting.  He has only been hearing for six weeks and already he can not only associate a sound with a particular object, but more importantly, can attempt to do the sound himself!  Go Henry!
