Kourtney Kardashian knows a thing or two about being a mom but she's not too sure if younger sister Kim knows what she's in for now that she is a mom.
According to Hollywood Life, Kourtney gave Kim a good reality check on what the future holds for the new mother. The older sister worries Kim believes her life is going to stay the same despite the new role she has acquired.
"[Kim] has no idea what she's in for as a mom. [She told Kim] her life is going to completely change and she's going to be totally surprised at everything," a source said. "Kim is about to be shocked at all the changes, and Kourtney knows this because she's been going through it for years."
The 34-year old claims her sister is not prepared for the upcoming change in her life.
"Kim thinks that she'll be able to do everything she did before and that her life will be as picture perfect as it always is, just with a little baby along with her," the source said. "Except Kourtney knows that isn't true - everything from her messy house to messy clothes and hair."
Kourtney, with her partner Scott Disick are parents to three-year-old Mason and 11-month-old Penelope.
Kim gave birth to a daughter on June 15. Reports indicate baby and mom are doing well. The baby girl apparently looks just like Kim. The 32-year old gave birth to her daughter five weeks early after coming into the hospital with complications and doctors were forced to deliver the child sooner than expected.
