On Wednesday's episode of Jake Shane's Therapuss podcast, she gushed that the 16-month-old is starting to explore new interests, like basketball and soccer: "He talks a lot about basketball. He says 'Basketball' all the time. I went to get him up from his nap today, and he was like, 'Basketball.' It's insane. So funny. He also just started, saying 'Please.'"
