This little girl drives me nuts

Deja

My sweet, mischievous little girl will be 18 months old in 4 days and shes been driving me nuts lol! She's starting to say no, back talk and her favorite word is mine. She can say momma, dad, grandma, papa, and sissy but she says momma all day long lol and even calls her daddy momma 😂 of course she doesn't listen unless anybody else is talking to her lol. Idk if it's because she senses that I'm pregnant again or what but she's not having it
