We missed the adorable moment between George and Charlotte yesterday

CUTE.

As you may be aware, the Duke and Duchess of Cambridge welcomed their third child yesterday and the royal birth was featured in publications all over the world. There was rolling coverage from multiple news outlets all day and of course, Prince George and Princess Charlotte arriving to see their little brother was the source of much attention. Everyone noticed's Charlotte's wave to the cameras while George was quiet and didn't appear to take too much notice of the crowds waiting at St Mary's Hospital. However, what many of us missed was the protective gesture George, who turns five in July, made towards his little sister, set to celebrate her third birthday next month. As you'll see in the below video, dad William ushered them in the front door of the Lindo wing and you can just see George outstretch his arm to his younger sister.

The name of the new Prince has not yet been announced but that hasn't stopped people from speculating what the couple will choose. At the moment, Arthur, Albert, James and Phillip are among the frontrunners and all will be revealed in 'due course' according to Kensington Palace.
