Princess Charlotte s first day of school was Thursday, and if you were worried she might be nervous to join her older brother George at the posh Thomass Battersea , dont be.

The young royal the Duke and Duchess of Cambridges middle child is already exuding confidence at the tender age of four. In an Instagram video released by Kensington Palace , Charlotte calmly shakes the head of the lower schools hand and then playfully flips her ponytail as the cameras click.

Her mother holds her backpack, which appears to be decorated with a key ring in the shape of a pony.
