Kim Kardashian West has admitted that it is "frustrating" not being able to carry her third child.
The 37-year-old star and her husband Kanye West - who have two kids, North, four, and two-year-old Saint - are expecting their third child via a surrogate, and the Keeping Up With the Kardashians star has tried to refrain from coming across as "controlling" to the woman carrying their baby.
She said: "It is frustrating like to not be able to do it on your own. It is a weird dynamic.
"I go to all the doctor's appointments and I try to be really present, but when you're not carrying it yourself it is such a fine balance of how much you're going to be in their lives.
"Of course, I want to know ever last detail that's going on with my baby and that's super frustrating, but I really trust my surrogate and I don't want to be that person that's trying to control her every move.
"It's going to be a long hard process but I'm going to take it one day at a time and hopefully it just gets easier."
Kardashian West admitted she is "really thankful" for her and Kanye's surrogate for doing such a "selfless" act, but she is hoping people do not find out the mystery woman's name.
Speaking in the latest episode of Keeping Up With the Kardashians on Sunday, Kardashian West added: "The fact that this is just what we can do these days, I'm like really thankful.
"I'm seriously so grateful for her and that someone is just so like selfless and kind to do this. And I definitely want to keep it private.
"I don't want people to find my surrogate. Like I don't want them to harass her. Like she doesn't know how to handle stuff like that, this isn't her world."
While the name of Kardashian West and West's surrogate has been kept under wraps, she is thought to be married and is the mother of two young boys.
The showbiz power couple are said to have hired the woman for $45,000 through an agency.
