I finally found our "little camera" that has a video function. Here's a sample of Nolan's speech at 23 months of age. It is quite long, so some of the captioning might not match perfectly with the video. He is probably above average for expressive language, but you can see his tendency to simply repeat questions rather than process the information and give an answer. I've heard this is not uncommon for hard of hearing kids, so we'll see what happens with a few more months of growth and speech therapy!
