King Cairo is already one adorable older brother for his future sibling-to-be.

On Thursday, Blac Chyna took to Snapchat to document her evening with her son and in one particularly sweet video, the expectant star lifted up her shirt to reveal her growing baby belly, only to have King Cairo reach out and rub it gently with a big smile on his face.

In recent weeks, Chyna has been open about how important it is to include King Cairo, 3, her son with ex Tyga, 26, in her pregnancy as she prepares to welcome a child with fiancé Rob Kardashian, 29.

“I kind of want to keep him in the whole loop of my whole pregnancy,” she recently told the Daily Mail at their yacht party in Cannes in June.

“I had to explain to him about the [engagement] ring, and what the ring means,” she added. “And what the baby means to me and the family, and [that] he’s going to be a big brother. He’s really excited about it.”

Meanwhile, any bad blood between Chyna and Rob’s famous family appears to be well and truly squashed. The model/business owner recently celebrated Rob’s sister Khloé Kardashian‘s birthday in Los Angeles with the rest of the Kardashian-Jenners, sharing endless pictures and videos on Snapchat of the women all getting along.

“The girls have really come around since Rob and Chyna first got together,” a Kardashian source told PEOPLE Tuesday. “They’re trying to be as supportive as possible, especially now that she is pregnant.”

“The girls are making an effort to put any drama behind them and make Chyna feel welcome,” added the insider.
