In the photo, she was seen standing with the boy, whose T-shirts each had their names written on them.

She also rarely posts photos of her children on Instagram, but she does post a lot of pictures with her husband.

McConaughey spoke about his parenting style on “Good Morning America.”

“Sometimes loving your children means giving them exactly what they want,” Matthew McConaughey said. “Sometimes it means tough love.”

“Wealthy people can give their children anything they want, but they usually don’t get what they need,” he said on the show. “Loving a child is much more difficult. . . “No” requires much more energy. It’s much easier to say yes.”

Although fans haven’t seen much of Livingston, the McConaugheys’ eldest son, Levi, has become an Instagram influencer with 329,000 followers.

His page says he’s “figuring it out.” Levi has shared photos of himself playing tennis, surfing, and other activities, and he sometimes shares glimpses of his siblings in family photos.
