Rob Kardashian and Blac Chyna may have been living in separate homes before the bootylicious personality gave birth, but now that daughter Dream has arrived -- the two are shacked up together, living under one roof again -- and it seems like the two are getting along!

An insider tells People, “Rob wants to live with Chyna and spend every day with Dream." The source added, “He is making a big effort to get along with Chyna. She seems very happy with him. They are getting along great and enjoying parenting together.”

Rob seems to be settling into life as a new dad to his baby girl, who is just three weeks old. “Rob is super hands on with Dream ... She’s changed his life. She makes him want to be better. And he’s spending a lot more time with his family,” added the source.

Despite the make ups and break ups the new parents seem to be getting along well now living together again in Chyna's home -- and if his Instagram posts are any indication, Rob's in seventh heaven with his new bundle.

“Rob is so much happier now,” says the insider. “He is obsessed with his baby girl!”

Aww! We're really happy to hear this, too bad we have a feeling that this won't last ...
