While some young siblings get jealous with the arrival of a new baby brother or sister, Kourtney Kardashian’s 2-year-old son, Mason Dash Disick, couldn’t be happier about his family’s newest addition, Penelope Scotland Disick.

“He’s in love with her,” Kourtney told Us Magazine (via Hollywood Life) in the magazine’s newest issue. “He’s always asking to hold her and cuddle her.”

“He’s adjusting to the whole thing so well. He calls her ‘sister,’” Kourtney added. “He gets mad if anyone calls her anything else. People will be like, ‘What’s your sister’s name?’ And he’ll say, ‘Sister!’”

Of course, life’s not all roses for little Mason.

“He’s having a lot of fun. He doesn’t like the smell of breast milk, though,” new dad Scott Disick explained. “It bothers him. He told Kourtney, ‘Mom, you smell like milk!”
