In a video posted Saturday by his mother, 5-year-old Ethan reacts to the news that he will soon be a big brother and asks his mother if it's really true nearly a dozen times.
He exclaims that he wants to tell his school teacher and help care for the baby.
His mother, 28-year-old Sarah Bromby of North Lincolnshire, England, will have the baby in January, according to the Scunthorpe Telegraph.
"I hope you're not joking," Ethan says in the video. "He can sleep in my bed, if you want."
