Blac Chyna's son King Cairo is clearly smitten with his baby sister Dream Kardashian.
The Rob & Chyna star posted on her Snapchat Saturday a sweet video of the 4-year-old kissing the child, who is awake and held in her mother's arms while swaddled in a newborn Velcro-sealed SwaddleMe blanket.
"I want to kiss my baby!" King Cairo says.
"Oh, she's smiling," he adds.
Blac Chyna and her fiancé and co-star Rob Kardashian welcomed baby Dream, their first child together, at a Los Angeles hospital five weeks ago and 10 months after they confirmed their relationship.
Their pregnancy journey was shown on the recent debut season of E!'s Rob & Chyna series and concludes with the Rob & Chyna Baby Special Sunday.
King Cairo had long been excited to become a big brother and showed his affection for her in his mom's social media clips. He was seen kissing Dream, then less than two weeks old, in a video posted last month. In a clip posted in late June, King Cairo gave his mom's baby bump a rub.
Blac Chyna and Rob have posted several photos and videos of their baby girl since she was born. In another clip posted on her Snapchat Saturday, Dream is seen sucking on a Wubbanub pacifier.
"My bestie," Blac Chyna wrote.
