Three days after the birth, Kim took to her app to reveal that the couple had made a decision to call their newborn daughter Chicago.The reality star shared a picture of the name, captioned with the date and time of the tot's birth, plus her weight - 7lbs, 6oz. The rapper and the reality star chose to use a carrier after Kim suffered pregnancy complications with her two older children.
She suffered from pre-eclampsia and placenta accreta in pregnancies for her daughter North, now 4, and son Saint, 2.
She wrote: "Having a gestational carrier is definitely different, but anyone who says or thinks it's the easy way out is completely wrong. It's not for everyone, but I absolutely love my gestational carrier and this was the best experience I've ever had", she said in statement on her app.
