Being a big brother is a big responsibility. Sure, you get mom and dad all to yourself for a little while. But then a new baby shows up. And another. You've got to show them what being an awesome brother is all about. But it can be stressful. There are no days off in the world of siblings. And with brothers like Caden and Carson, two energetic younger brothers can be exhausting work. Which is possibly the reason the news of a set of twins on the way wasn't taken with smiling excitement. We're sure when the time comes, he'll love his new siblings and continue to be the standard-bearer for this growing family. We're also pretty sure that at some point Carson will believe in the existence of twins.
