Kim Kardashian shared her first photo with niece Dream on Tuesday.
"Hey beautiful girl," she captioned the snapshot for her 94.4 million followers.
Dream has appeared in previous posts of Kardashian's, but never with the mom-of-two herself.
People reported in November that Kardashian, who shares 3-year-old daughter North and 15-month-old son Saint with Kanye West, is thrilled to have a new niece.
"Kim takes her job as an aunt very seriously. [She] was excited to spend time with Dream. She loves babies and thinks Dream is the cutest," a source told the magazine.
"She is very proud of Rob and how seriously he takes his job as a dad," the insider added.
Rob and Blac Chyna welcomed Dream on Nov. 10 after getting engaged in April.
The 29-year-old reality star gushed about his daughter in a new post Monday after reportedly splitting from Blac Chyna again in February.
"Look how long her eye lashes are," he wrote. "I will never say no this Woman lol."
She was spotted at her usual pre-natal clinic in January.
