Well that’s just too adorable! Everyone may know him as Prince Louis, but Prince George and Princess Charlotte have the cutest nickname for their little brother.

According to Life & Style magazine, George, 5, and Charlotte, 3, call their baby bro, “Lou Lou.” Perhaps that’s a reflection of how the now 1-year-old is.

“Louis has already developed his own little personality. He’s very chill and relaxed,” an insider tells the outlet. “But he’s also strong natured. When he doesn’t get his way, everyone knows about it!” It was Lou’s birthday on April 23, and it’s amazing to see how fast he has grown — just the other day he was using a “little walker.”

“Louis just wants to pull himself up all the time,” his mom, Kate Middleton, gushed to some parents while playing around with their kids at the Henry Fawcett Children’s Centre on March 12. “He has got these little walkers and is bombing around in them.” Kriti, a mother at the event, told reporters that the 37-year-old royal noticed how similar her 9-month-old son Kameron was to Louis.

“She took one look at Kameron and said, ‘Oh, he wants to go walkies.’ Apparently, her son is cruising, and she said she was running after him all the time,” Kriti added.

It is no surprise at all that the Duchess of Cambridge, 37, is all about her kids — the source says that she and her husband, Prince William, focus on “family,” and that that “means everything” to the pair.

As for the nicknames, perhaps that fun was kicked off by the kids’ grandmother, Queen Elizabeth. “When I met her at a semi-private party, and everyone had a nickname — she spoke in riddles and this is what it feels like to be one of her friends,” Ingrid Seward, the Editor-in-chief of Majesty Magazine, once said on the Yahoo online series, Royal Box.

Runs in the family it seems!
