Scott Disick is giving Rob Kardashian a taste of what it's like to be a father.
In a promo for Sunday's season finale of Keeping Up With the Kardashians, which was taped before Rob's fiancee, Blac Chyna, gave birth to their daughter, Dream, last week, Scott takes the 29-year-old reality star to a daycare to show how stressful it can be as a parent. "I wish I could say that only sometimes parenting is chaotic," he says. "But it's pretty much all the time, 24 hours a day. ...It's just difficult all around."
"Get ready, Rob. This is about to be your life," Scott tells Rob while he's trying to get the kids to stop crying.
While Scott -- who has three children with Rob's sister, Kourtney Kardashian -- admits that his friend has lots to learn, he's confident that Rob will make a great dad. "You're a goodhearted person and you're going to be a goodhearted dad," he says.
"At the end of the day, he definitely has the heart of a parent," Scott adds. "And I think he's going to be an unbelievable one."
