Rob Kardashian and Blac Chyna are already planning for a second child ahead of the upcoming arrival of their first baby together. Kim Kardashian's brother wants to have an even bigger family than his own Kardashian-Jenner clan.

Rob reportedly wants more children than his late father Robert Kardashian. "Should everything go well with Rob and Blac's first pregnancy, they're heading down the aisle and back to the bedroom to get it cracking," a source reveals, "Rob wants more children. He wants to have at least as many children, if not more, than his late father."

"Rob comes from a big family but for many of years of his life he felt exiled from them. Part of the reason he wants a massive family of his own is so that he can not only spread a lot of love to Blac and their kids, including King, but also to feel loved by them. Blac's down too. She and Rob are so much in love and on the same page when it comes to just about anything," the source tells HollywoodLife.com.

Blac is currently around 5 months pregnant with Rob's baby. Earlier this month, the couple announced their own show "Rob & Chyna" and a separate TV special to celebrate the birth of their first child together, which will air on E! later this year.
