Why Can't You Hear Me?

Are you deaf? Are you DEAF? I said that at the top of my lungs as loud as I can, right in front of him and still NO response. He stared ahead at the TV, without a twitch. Let's go back, a couple minutes beforehand I was calling out his name and he was not paying attention or so I thought. I finally became so frustrated that I shouted, "Are you deaf?", and still nothing. I could not help it. I did not know what was happening. I did not know what was going on. Why isn't my son responding? Oh my goodness, can he hear me?  Is this why he is not talking? Is this why  he does not babble or ask for things. You see, he was three years old. He has not yet spoken in a complete sentence. He could not tell you his name. He was non verbal. I believe he had said a few words, but that stopped. Then, nothing. It was literally a few words from what I can recall, then absolutely, nothing. He did not wave bye bye, was still in diapers, did not say his name and could not answer what was asked of him. What is going on? My son can not hear me. Fast forward, he has fluids in his ear and has decreased hearing because of it. Only about 20% capacity. We move along. He gets diagnosed with autism, we move along. Fast forward, he gets tubes in his ears and we move along. His speech begins to come and we move along. He hears better and that is why he is beginning to speak because he can now hear what is going on in the world around him. We move along.Blessings in disguise....
