The reality TV star and fiancée Blac Chyna welcomed daughter Dream Kardashian into the world earlier this month but the tiny tot is already busy promoting her father's business.

A video of Dream on her own Instagram account shows the tot wearing a pair of socks from Rob's Arthur George line, with the caption: "I love my new @ArthurGeorge87 socks from daddy!!! @robkardashian."

Meanwhile, Rob's mother Kris Jenner recently said it has been "a joy" to see her 29-year-old son become such a loving dad.

She said: "The baby is so fabulous. He's so nurturing, and he's such a care giver and such a sweet man. It's really been such a joy to watch him go through this."

She admitted previously: "It's always so exciting when your baby has a baby so it was really great. It's really emotional. Like you can't believe that this is happening. To see a baby being born and in my case, I've been there for six of my grandchildren's births so it's quite something.

"Dream's such a great baby though. She's been really calm and really sweet so they are very lucky."

And Rob's sister Kylie Jenner said she gets emotional seeing pictures of Rob and Dream together.

She said: "The photos with Rob and his daughter literally make me want to cry.

"All the photos make me want to cry - the family photos, the photos of just her, but it's really sweet. She's so cute."
