Ears of Corn

Amerie came over today while I was getting dinner ready. I just finished husking the corn. When I asked what is that holding up a piece of corn. " An Ear of Corn" matter- factly she said. Oh do we hear with this ear? "No" she answers. then why do we call it an ear. "I don't know ".
Then she counted the ears of corn for me.
When did my little toddler get so big to carry on a conversation. I feel like it was just yesterday she was just being to say one word phrases.
