Laughing while sat with her cuddly toy dog, Princess Charlotte looks pretty in pink in pictures released to mark her six month milestone.
Two official pictures have been published of the Duke and Duchess of Cambridge's daughter to thank royal fans for the good wishes sent to the couple.
The photographs were taken by Kate at their family home Anmer Hall in Norfolk early in November.
Kate is an accomplished amateur photographer and took a joint portrait of her children George, aged two, and Charlotte a few weeks after her daughter was born on May 2.
The last time the princess was seen in public was in July during her christening at St Mary Magdalene Church on the Queen's Sandringham Estate in Norfolk.
In the first picture released, the baby is shown sitting in a chair with her toy and is howling with laughter as her mother snaps away with the camera - believed to be the same Canon EOS 5D Mark II she used for previous shots of her children.
In the second image the princess is shown looking past the camera as if something has caught her attention behind the Duchess.
Charlotte is believed to be wearing a pink cashmere cardigan over a Liberty print dress with a frilly collar.
Babies of Charlotte's age are making major strides in their development and the princess appears to have reached some of her targets - sitting up, laughing and engrossed with the world, and is likely to be gurgling and able to roll around unaided.
