Since Charlotte's arrival into the world in 2015, the Princess has captured our hearts with her cute smile, pretty outfits and close bond with mother Kate. Princess Charlotte was the most adorable baby - cheerful in pictures and often looking to her royal mum for reassurance when she was a toddler.
Now age seven, the Queen's great-granddaughter is becoming a charming young lady who Prince William and Kate are sure to be proud of.
Here, we take a look back at 15 of Kate and Charlotte's sweetest moments together…
