The feud appears to be settled when the baby wearing the green trousers realises that she can avoid the grasp of her sister if she turns her head to the side.

While the video has melted the hearts of many online, others have questioned why both sisters weren't given a pacifier of their own.

The video, which dates from four months ago, provoked a strong reaction after recently being posted by Italian Facebook page Love E Beautiful, where it has been viewed two million times.
