"I'd lose my mind if I heard my kid call the nanny Mommy"

In this quote, Toni Braxton reveals her strong sensations about the idea of her kid calling someone else "Mommy." As a mom, she likely has a deep psychological connection with her child and the idea of them forming a similar bond with another person is disturbing to her. The use of the word "lose" suggests that this situation would greatly affect her frame of mind, potentially triggering her to feel overloaded and even go into a state of panic. This quote highlights the strong maternal impulse and protective nature that numerous moms have, and the idea of somebody else taking on that role is difficult for Braxton to picture.
