The 29-year-old reality star shares three-month-old daughter Dream with his former partner, and despite taking some time away from one another, the pair are still determined to remain amicable for the sake of their young child.

A source told 'Entertainment Tonight': "They are doing the best they can to stay civil and to co-parent the best they can. They have worked out an informal custody arrangement. They found out what works for them and they're doing a good job at it.

"[Rob and Chyna] realise Dream will connect them for life, and it's not worth it for them to fight and get dramatic about their breakup. They're forever connected by that beautiful girl, so there can't be any bad blood."

The news comes after it was previously reported that the 'Keeping Up with the Kardashians' star and Chyna, 28, are "in a better place now" they have gone their separate ways.

A source said: "Rob had been staying at Kris' house with the baby while Chyna was out of town and Kris was helping him with the baby. He's in a really positive mood again.

"Everything was moving so fast with the relationship, the baby, the engagement and the show that this break has been really good for both of them. Now that they've had space, we'll see if they end up getting back together, but for now, they are still happily separated. They are both much happier and in a better place right now."

Meanwhile, Rob's mother Kris Jenner also appeared to admit previously that the pair's relationship was tumultuous at times.

Speaking about the pair - who got engaged after four months of dating - she explained: "You know, I think that, too, is a work in progress and they have good and bad days. It's a young relationship and they haven't known each other for that long."
