Mine is a mix........Unless my child had auditory nereopathy, I would wait until they were a little older to be implanted. That's b/c I don't trust technology, giving us an accurate picture of a baby's hearing. I've heard of kids being dx as having "deaf" losses, on ABR and then they were found to have hoh losses on more traditional autotremy tests. For my child CI would be the absolute last resort.....only if they had REALLY REALLY bad losses....If I did have to implant them, then I'd make sure it was before their third birthday, so they could still benifit, but still make sure they had the correct loss.
