Everyone had a different opinion. The pediatricians thought that she would talk when she was ready. In the meantime, her two older sisters were doing the talking for her.
The psychologist thought she was selectively mute. I later found out this happens with severely abused children! My mother-in-law thought she was just stubborn.
We enrolled her in a pre-school for children with communication disorders. One day the teacher would write that, "Yes, she definitely hears." The next day another noted, "We don't think she is hearing us."
Jessica was a happy funny kid but would have TERRIBLE temper tantrums when she was trying to tell us something. She had night terrors and once I caught her crawling out a window in the middle of the night, sleepwalking. I was at my wits end and also nine months pregnant with my fourth child.
I finally got permission from my doctor and insurance company to have an ABR [Auditory Brainstem Response, an ‘evoked potential’ test with electrodes measuring the brainwave responses to sounds, which does not require a behavioral response from the child-Editor’s note]. At the hospital where it was performed, they, at first, did a regular hearing test. They came out and said she passed and don't bother with the ABR. I insisted. They said it would take an hour. Three hours later they came out and said they wanted to continue sedating her and did it a third time.
It turned out she had a severe hearing loss. They said they had never had a child fool them like Jessie had. My initial reaction was relief. I knew something was wrong and finally I knew what it was. I then went about trying to learn more.
