Everything We Know About Kim Kardashian and Kanye West's Life With Baby Chicago

The couple welcomed baby No. 3 via surrogate on Monday, giving North and Saint a baby sister!

Kim Kardashian and Kanye West have themselves a pretty full house!

The couple welcomed their third child, a daughter, via surrogate at 12:47 a.m. on Monday morning. Kim revealed the news on her website, noting that their "healthy, beautiful baby girl" weighed in at 7 lbs., 6 oz., and that her older siblings, 4-year-old North and 2-year-old Saint were "especially thrilled to welcome their baby sister."

On Friday, Kim finally unveiled the baby's name on her website: Chicago West. She also shared on Twitter that the baby is named "Chi" for short.

“The family is home and happy. Everyone is settling in nicely," a Kardashian family source tells ET.

On Wednedsay, an additional source told ET that Kim and Kanye quietly checked out of Cedars-Sinai Medical Center in Los Angeles on Tuesday.

“The baby is at home,” the source said. “Kim, Kanye, North and Saint are enjoying every second of bonding time with the new baby.”

A source tells ET that Kim was the first to make "skin-to-skin contact" with the child followed by Kanye, adding, "Kanye was in the delivery room but behind a curtain. He immediately held the baby after Kim received her." The source adds that there were no complications.

A separate source tells ET that Kris Jenner and Kim’s sisters joined the couple at Cedars-Sinai, but were not in the delivery room for the birth.

"The family is so excited and feels so blessed," a Kardashian family source tells ET. "She is an angel!"

On Tuesday, Kanye was seen heading into the office following his baby daughter's arrival. The 40-year-old musician looked to be in good spirits, even flashing a piece sign for nearby photographers.

The smooth delivery process is certainly a relief for the couple, after both of Kim's pregnancies were high risk and fraught with complications.

Kim, 37, suffered from early-onset preeclampsia with North and had to deliver almost six weeks early in 2013. Her 2015 labor with Saint also had complications, with Kim suffering from placenta accreta, where the placenta remains attached to the wall of the uterus. The latter condition occurred during both deliveries. The difficult deliveries were a big part of the couple opting for surrogacy this time around.

In November, Kim admitted in an interview with ET that surrogacy had been much harder than she anticipated.

"You know, it is really different," she shared. "Anyone that says or thinks it is just the easy way out is just completely wrong. I think it is so much harder to go through it this way, because you are not really in control. And, you know, obviously, you pick someone that you completely trust and that you have a good bond and relationship with, but it is still ... knowing that I was able to carry my first two babies and not, you know, my baby now, it's hard for me. So, it's definitely a harder experience than I anticipated just in the control area."

"I hated being pregnant and I never thought I'd ever ... I thought this was going to be so easy, but you know,  even in how much I hated it, if I could do it myself I would have preferred that," Kim confessed. "So, that inner struggle is kind of hard, but I am just rolling with it and it is what it is."
