Taken by Kate back in April, the photos show the adorable tot playing inside as well as out in the garden, in one photo she is seen pushing along a wooden toy cart with the giant grin on her face.
“The Duke and Duchess are very happy to be able to share these important family moments and hope that everyone enjoys these lovely photos as much as they do," said a statement from Kensington Palace.
While Wills and Kate have expressed their desire to keep Charlotte's birthday low-key, it seems the world has other ideas.
The Palace have released a list of the gifts the Princess has received since her birth on May 2, 2015, and it's extensive to say the least.
Topping the list however is an 18k white gold rattle which is covered in diamonds and rubies and sapphires from the Natural Sapphire Company and is valued at £30,000 (approx $57,500).
