There's very little more exciting than the prospect of welcoming a new life into the world, but we sometimes forget who else gets a cute of happiness from that impactful moment: the sibling waiting for their new companion in life and partner in crime!

Such is the story for this little girl, who, judging from her reaction, has been waiting outside impatiently (understandably so!) for the opportunity to see what's going on inside the hospital room. "What happened?" she asks, before immediately losing herself in bliss as she comes to realize that her new baby brother is right in front of her. Watching her go from confused to ecstatic in an instant is a must-see to believe feel-good moment!
