Getting ready for the big day!
Blac Chyna seems to be doing a great job preparing her son, King Cairo, for the arrival of her new baby, and posted an adorable video of the 3-year-old that demonstrates just how excited he is for big brother duty.

In the clip, King — who's dad is Chyna's ex, Tyga — is seen rubbing his mother's blossoming belly as they relax on the couch.

The reality star and lash entrepreneur recently said she's doing her best to prepare King for all the big changes to come, including her upcoming wedding to Rob Kardashian. “I kind of want to keep him in the whole loop of my whole pregnancy,” she 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.”
Couldn't be more excited for this family.
