If you’re an older sibling, you may not remember the moment you found out that you were going to be a big brother or sister. I’m the youngest of two and I’m lucky to have a great big brother, but I doubt that he was excited as the boy in this video when he found out the news. He settled into the role and was a wonderful, protective older sibling and friend, but I imagine the news of my impending arrival must have been a bit of a shock.

Five-year-old Ethan was just shown sonogram pictures of his new baby sibling growing in his mother’s belly. His reactions go from incredulous to pure excitement, and he asks over and over if it is true. He can’t wait to share the news with one of his favorite people, his teacher, and seems delighted with his upcoming role as big brother.

Watch Ethan’s adorable reaction in the video below and please like and share the post if you found this heartwarming and adorable!
