Twin babies have proved that you're never too young for a spot of sibling rivalry as they squabble over a dummy in a cute video.

The sisters, believed to be from the US, can be seen taking the pink pacifier out of each other's mouths in a video uploaded by Baby Clips Daily with more than 750,000 views on YouTube.

But as one takes the comforter, the other is left uncontrollably crying until she retrieves it again.

The baby in the green trousers starts out with the pacifier in her mouth, but her twin soon swipes it away

It leaves her sister upset and getting into a bit of a flap as she works out how to retrieve the comforter

Dressed in matching white T-shirts with contrasting green and beige trousers, the twins pass the pacifier between themselves four times in the clip.
