Reality TV stars Kourtney and Khloe Kardashian are obsessed with their niece - North West.
Kim gave birth to her and her beau Kanye West's first child Nort West last month and her sisters Kourtney and Khloe love spending as much time as they can with the baby, reports femalefirst.co.uk.
"Kourtney and Khloe are obsessed. Kourtney has been great with advice, from baby gear to reassuring Kim in all her decisions. The family is really supportive," a source told People magazine.
Kourtney, who has two children - Mason, 3, and 11-month-old Penelope, with Scott Disick, has also introduced North West to her cousins.
Kanye has been capturing every moment of his daughter's life and is rarely seen without his camera.
"Kanye wants to know how to do everything and be able to hold and soothe her. He's been documenting everything. He doesn't want to miss a moment," the source added.
