Update for this week ....
The audiology appointment went well. He still didn't want to look at their stupid poxy puppets (!) in response to sounds, so they decided to try and monitor his facial expressions instead - smiles, head turning as if looking for the source, eyebrows raising, even to the point of squawking when sounds were too loud.
The good news is that he does have some hearing in his left ear
The loss is greater than in his right, but he's not profoundly deaf, and it means that - with correction - he'll have a sense of where sound is coming from (because that relies on both ears hearing slightly differently).
Because he didn't perform well with the puppets, they want to repeat the testing to make sure they didn't interpret smiles at the toys, or even wind (!), wrongly as reaction to sound. They took fresh ear moulds and, when we return in January for tests, they'll programme the next set of hearing aids to match his responses. Then he'll go home with aids again.
Now that his development is improving (sitting, playing), it will be interesting to see whether the aids change his behaviour - will he become more aware of us, and of the television?
His daddy shouted across the room to him earlier today (in fun, not in anger) and Andrew was turning his head and laughing in response. So it would seem that he is *now* responding to sounds
