It can be difficult for any kid to fully grasp the awesomeness of being an older sibling, especially when dealing with the shock of no longer being the baby. Lucky for Sarah Bromby, her son Ethan is way ahead of the curve.

When she broke the news to Ethan that he was going to be a big brother, he could hardly contain his excitement. He's so thrilled he almost doesn't believe her, as can be seen in a Facebook video posted on August 21.

"I hope you're not joking," he tells his mom. Once she assured him, he exclaimed, "I'm so happy with the baby coming out!"

His reaction in the clip below is basically all of our spirit animals.
