“Kim lives right across the street, Kylie and Rob are just a few minutes away and Kourtney and Khloé are only a five-minute drive. Khloé throws weekly parties and get-togethers for the cousins, it’s the cutest thing,” she adds.

While Jenner can’t get enough of all the little ones running around, she’s even more thankful for the friendships her grandchildren will forge as they grow up.

“As blessed as I am to have all of my grandkids, they are beyond blessed to have each other,” she tells PEOPLE. “They will all have best friends for life.”

Jenner has passed down her love of gift-giving to her family, who she says give each other special items even when it isn’t someone’s birthday or a holiday.

“Sometimes you see something that makes you think of someone and the best gifts are often those heartfelt, random gifts that let someone know you’re thinking of them,” she tells PEOPLE.

In particular, the Keeping Up with the Kardashians star has made it a tradition to give each daughter a “sentimental gift” the day their child is born.

“I gave Khloé diamond bracelets that her father had given to me on the day she was born. I had been holding on to them for the day Khloé had her first baby,” Jenner says. “Natural diamonds never lose their value, so I know my children can pass those pieces down to their children.”
