MY = I

Brenna learned how to talk from her cousin Tucker that is 9 months older. Right now his I's = My's. "My want that toy". Brenna speaks the same way now. I have been trying to help her talk correctly but it is not sinking in:

Brenna: "My want it" (her pink hat)
Mom: "Brenna say, 'I want it'"
Brenna: "You want it?"
Mom: "No Brenna (in a higher tone this time) say, 'I want it'"
Brenna: "No its my hat"
Mom: "Yes, it is your hat, but dont say 'My want it' say 'I want it'"
Brenna: "You want it? Okay here you go mama"
