Also- learn to use quotation marks in your question, to distinguish the parts of your sentence that are being spoken by each speaker. In your question, it appears that moms are accusing you of having eyes in the back of your head. I don’t think that’s what you meant. And yes, it is really weird.

Either that or they talk about needing to have eyes in the back of their heads when, for instance, they’ve got a toddler who needs watching all the time.

Children, and young people give these little clues, and they do not even know they are doing so, but that works in our favor.

My mom used to tell us, besides the eyes in the back of her head, her x-ray vision could see through walls as well.

When I was little I was jumping on a bed one time, and my mom had her back turned and she said stop doing that and I said how did you know i was doing that and she said cuz i have eyes on the back of my head

This refers to our sixth sense, which relies on all 5 senses.
