As many parents will attest, picking out the perfect name for your baby can be tough— just ask Kim Kardashian.

The reality star/mogul and her husband, Kanye West, welcomed their third child to the world via gestational surrogate. The couple faced obstacles when trying to decide on a moniker, but ultimately named their daughter who was born in January, Chicago West.

The pair announced Chicago's arrival via Twitter, with a detailed explanation the following day on Kim's app. She stated, "Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl. We are incredibly grateful to our surrogate who made our dreams come true with the greatest gift one could give and to our wonderful doctors and nurses for their special care. North and Saint are especially thrilled to welcome their baby sister."

Kardashian recently made an appearance on The Ellen DeGeneres Show, where she went into detail about the difficulty of choosing a name for their baby.

Ellen asked Kardashian to clarify on her earlier statements about her daughter's name saying, “So her name is Chicago but you told me you wanted a one-syllable name…”

"We were gonna name her Jo 'cause my grandma [is] Mary Jo," explained Kardashian. She added that they were also considering the name Grace. "And then it was Chicago. We ended up with Chicago. Obviously [Kanye's] from Chicago. That is a place that made him and a place that he remembers his family from."

Kim continued to explain that Kanye had also wanted to name their baby Donda, after his mother who died in 2007 from surgical complications. She said, "He really wanted his mother's name, and I love that name, too, I just wasn't sure if [it was] so much to live up to."

Chicago joins her two older siblings, brother Saint (2) and sister North (4).

Kim confided in DeGeneres more details about her experience with surrogacy. Her first two pregnancies she carried to term, but doctors were concerned about her health if she tried for a third. Kardashian suffered from preeclampsia and placenta accreta, both serious conditions that pose potential fatality for mother and baby.

“Anyone that has ever been considering surrogacy, I always said, ‘Wait until I’m done, I want to see what this birthing experience is like,'” Kim told Ellen. “[It was] the best experience! The moment she was getting the epideral I was like, ‘Thank God this is not me.’ It was so easy.”
