Matthew Stafford's wife, Kelly, opened up about the changes in her daughter's behavior as she ages. On "The Morning After" podcast, the NFL star's wife talked about parental duties and how she has been struggling.Kelly, a mother of four daughters, said that one of her girls had started "disrespecting coaches" and "walking away while they're talking to her."“One of my daughters I have been very, very much struggling with,” Kelly said (via E! News). "She has become a little girl that I don’t recognize. Right now, I’m trying to be mild with it.”She recalled an incident in which one of her daughters, Tyler, complimented another daughter on her dress. However, the other daughter turned to Tyler and said that she looked "gross," which made the younger one burst into tears.“I’m like, ‘I have tried everything,’” Kelly told her daughter at the time. “’I have tried sitting near your room. I’ve tried taking things away. I have tried just talking to you like a young woman that you are. Nothing is working. I’m exhausted.’”Matthew Stafford and Kelly welcomed twins Sawyer and Chandler in 2017. A year later, they welcomed another daughter, Hunter. Their youngest, Tyler, was born in 2020.Kelly often shares the growth of her daughters and fun-filled outings with them on social media.
