It's an unforgettable time for the Kardashian family.
Rob Kardashian and Blac Chyna welcomed their baby girl, Dream, last month, and in a sneak peek of the Rob & Chyna Baby Special airing Dec. 18 on E!, cameras capture the exact moment Rob sees his baby girl for the first time. Rob is in the delivery room and wearing scrubs, as his mother, Kris Jenner, says in the background, "This is Dad!"
The preview also gives fans a look at Chyna's lavish baby shower, as Scott Disick hilariously observes, "I thought this was a chill thing. I didn't know this was, like, the Oscars."

The Rob & Chyna Baby Special will bring viewers into the delivery room and focus on the complicated journey the couple takes as they start their new family.
But it appears 29-year-old Rob is loving his new role as a doting dad. On Thursday, Rob Instagrammed a super cute photo of Dream, who turns one month old on Saturday.
"Hi baby :)" he captioned the pic of his giggling daughter.
