The 44-year-old reality star - who already has Mason, 13, Penelope, 11, and eight-year-old Reign, with former partner Scott Disick - welcomed her first child with husband Travis Barker, 47, earlier this month, but an insider has claimed that her sisters Kim, 42, and Khloe have not met their nephew yet, nor has Kris Jenner met her grandson.

A source told The U.S Sun: "[Kourtney] and Travis have communicated that they will be taking 'family only' time for the newly blended family and for Kourt to rest, and then they will be inviting the extended family over on an individual basis."

The insider went on to add that while Kris is expected to receive top priority and come first on the list, it has left the left of the world-famous family wondering just when they will get to meet the little one but it is said to be all part of the Poosh founder's plan to "protect" the little one from germs.

The source said: "So now everyone's talking about where Kim will be on the list. Obviously, Kris will be first - but who is going to get the second invite? Kourtney has said it's a germs thing - to protect the baby and not expose him to any risk - but it's, like, part of her new strategy to keep everyone at arm's length."

Little is known about the birth itself but just days before the baby arrived, Travis - who also has Landon, 21, and 17-year-old Alabama with ex-wife Shanna Moakler - was seemingly confirmed that he and 'The Kardashians' star had chosen to name the newborn Rocky when he arrived.

At the couple's baby shower guests were encouraged to leave messages for the baby, one named the then-unborn tot Rocky.

It read: "May Baby Rocky have … life filled with love."

The drummer had previously revealed it's his dream to call his son Rocky Thirteen after Rocky George from hardcore metal band Suicidal Tendencies and boxer Rocky Balboa (Sylvester Stallone) from the 'Rocky' and 'Creed' movies.

Speaking to Toby Morse on the 'One Life One Chance' podcast, he slipped up: "There was a benefit in Hawaii that we were gonna do, but it’s the week that Rocky’s due."

The host then said: "Rocky Thirteen Barker," to which Travis repeated: "Rocky Thirteen Barker!"
