Hearing test

Littlest boy didn't pass his hearing test when he was born. The tested him twice at the hospital, and then told me I had to take him to the ear doctor to be tested again.
Crazy how it works. And I don't really know how it does, but they put a little ear piece in his ear and it sends out sound waves and the machine can tell you if the baby hears it or not. I don't get it??! But…
She tested his ears. The left ear was fine, the right ear didn't pass. So she tried again…and again. It took three tries before he finally passed. She said sometimes the ear piece doesn't get in there quite the right way, and some babies ears are more sensitive than others, obviously. He slept through the whole thing and She got him to pass before we left…phew!!
