Babies and the Elderly

What is it with the elderly and babies? I made a quick stop at the market today. I noticed someone following me in the produce isle. Abigail was in her car seat on my arm. I turned around and there was a little, elderly woman nose to nose with Abigail. "He's so cute and quite!" I smiled and told the woman that SHE was very sleepy. I moved over to the tomatoes when I heard someone asking, "What aisle did you get that in?" Now there is an elderly man peering into the car seat. Once again, "What aisle did you get that in? He's cute." Now I'm a bit frustrated, I just smiled and said SHE was sleepy and have a good day. I don't understand the confusion. Abigail was wearing her pretty hat. I don't think she looks like a boy.
