My daughter, Abigail is two and a half. She recently learned a phrase commonly used by 2 year olds known as, "That's mine."
Abigail was explaining to me that she possessed something that she didn't particularly want to share and stated, "That's mine's."
I said, "No Abigail, It's 'mine.'"
My intention was to emphasize that "mine" is singular, not that her posession belonged to me.
To this she responded, "No Mommy, It's mines!"
I could tell this wasn't working, so I restated my point by emphasizing the singularity of the word "mine."
"Abigail, you need to say, 'It's Mi-ne (my nuh).'"
Instead of saying, "It's mine's," Abigail now says, "It's mine nuh"
