This video is sure to bring a smile to your face.

Some parents in Colorado posted a video to YouTube of them breaking the news to their kids about getting a new baby brother or sister.

At first, the parents attempt to give the kids clues before breaking the big news. Dad tells the kids, ”You guys are going to have another brother or sister!” “You have a baby in your tummy right now?!?” is the little girl's adorable response.

She squeals with glee as she hugs her mom and then says, "I can't thank you enough!" Little brother seems slightly less excited.
