"Be there the day Kim becomes a mom," says the voiceover in the sneak peek for tonight's episode of Keeping Up With The Kardashians.

Kim Kardashian is frantic when the time comes to deliver her baby in Sunday's episode titled, All Signs Point To North. It is five weeks before her due date, she learns she has toxemia so she has to deliver her first child right away.

Khloe Kardashian tells the cameras in the preview that her niece's early arrival is "definitely scary" for them.

Khloe is on the phone with Kim who tells her she is upset because their mother is not answering her phone and her boyfriend Kanye West is on a flight to come to Los Angeles so she feels alone.

Khloe calls their mother and when she finally answers the phone, she quickly comes up with a plan on how the family can go into the hospital without paparazzi catching on.

Khloe suggests that Jenner goes to Kim's house and takes her to the hospital while she heads to older sister Kourtney's home so they could both be on standby.

Kourtney says all she and Khloe can do is wait at her home until they are needed.
