People Editorial Guidelines Published on July 18, 2018 04:32 PM Share Tweet Pin Email Princess Charlotte is a proud big sister — just like her great-grandmother! The 3-year-old captured hearts in the official portraits from Prince Louis‘ christening when she sat next to mom Kate Middleton and couldn’t take her eyes off her baby brother. She even adorably held his hand for a group shot with all the royal family members. Charlotte has been taking her duties as a big sister seriously from the start. In an adorable photo of the pair taken just nine days after Louis’ birth on May 2 (Charlotte’s birthday), Charlotte cradles Louis in her lap and places a sweet kiss on her sleeping little brother’s head. Charlotte’s adoration for her baby sibling is reminiscent of Queen Elizabeth‘s own duties as an older sibling to the late Princess Margaret, who was four years younger than the monarch.

In a portrait with their mother from around 1930, Elizabeth places a protective hand over her baby sister. As they grew up, their close relationship continued to show. In a picture of the sisters hugging from 1932, Margaret snuggled in close next to her older sibling, who held onto the little one’s arms. The Queen also made sure to steady the toddler during a joint ride on a rocking horse.

She proved to have inherited the very best of the 92-year-old monarch in school photos released back in January — from their captivating gazes to their matching hair part.

More recently, the little princess was seen enjoying a day in the sun at the Maserati Royal Charity Polo Trophy at Beaufort Park — where dad Prince William was playing in a charity game. She was rocking little pink sunglasses that perfectly matched her dress, practically twinning with Queen Elizabeth, who was spotted wearing dark sunglasses in May while recovering from a procedure to treat a cataract.
