After a tumultuous journey, Rob Kardashian and Blac Chyna are finally enjoying their new role as parents to baby Dream. The new member in the family reportedly played a huge part in bringing the couple together.

According to HollywoodLife, there is so much of love brewing between the two that Chyna is apparently in "tears of joy" when she sees the Arthur George sock designer doting over her baby daughter.

"Chyna couldn't be happier for Rob. She can't believe her eyes when she sees how magical the bond is between he and Dream. She cries tears of joy because she knows Rob's the happiest he's ever been in life. They're so happy now and can't wait to be married," a source told the website.

The couple, who have their own reality show Rob & Chyna on E Network, were reportedly living apart due to constant fights. But after their daughter's birth, the dynamics between the couple have changed for good with friends of Rob claiming that he was "born to be a dad". The 20-year-old reality TV star is even singing lullabies to baby Dream.

"He's so in love with his daughter and has taken his daddy duties to the extreme. He does everything! Changes diapers. Bathes her. He's up in the middle of the night when she's crying. He even sings cute little songs to her to put her to sleep. Rob is such a natural dad. He was born to be a father," a source told the website.

The father-of-one has taken his role so seriously that he even included Dream in advertising his latest Christmas Arthur George sock collection. In the adorable video, two-week-old Dream looked angelic, dressed in white, while lying in a red Santa car seat.
