Rob Kardashian shares smiling photo of baby daughter Dream Kardashian

Rob Kardashian has taken to fatherhood like a dream and like most proud fathers has shared a photo of his little girl on Instagram.

The 29-year-old became a first-time parent following the birth of his daughter Dream Kardashian on 10 November at Cedars-Sinai Medical Centre in Los Angeles.

Prior to her birth, the reality star became increasingly reclusive as his battled with his weight, however ever since he and fiancée Blac Chyna have welcomed the new addition to their family, Rob has been embracing social media like never before.

On Thursday (8 December) the Keeping Up With The Kardashians star posted a smiling photo of his daughter to mark the first month of her life.

While Rob initially expressed his concerns about becoming a father, he is now every inch a doting Dad. "Sleep baby .... best thing that has ever happened to me in my life," he posted.

The adorable photo was a welcome distraction from the legal battle between Chyna and Rob's sisters Kim, Kourtney and Khloe who are embroiled in a dispute over Chyna's plans to trademark her name as Angela Renée Kardashian, once she ties the knot with Rob.

TMZ reported that the Rob & Chyna star wants to use her fiance's surname to accelerate her business ventures and has been left heartbroken by their opposition.

Chyna's lawyer was 'shocked' when the Kardashians opposed her request to trademark what will be her married name. Lawyer Walter Mosley told People that of the many trademarks he has filed for her, "this is the first one that's ever been opposed. I think for us this is going to be a clear case win, because it's actually her name, it's not a poaching".

Dream's birth is the focus of an hour-long baby special airing December 18 on E!
