Since 2007 the Kardashians have been building their empire thanks to their reality show Keeping Up With The Kardashians. But before they invited the rest of the world to enter their homes and lives, this family had a surprisingly normal off-camera life, or at least for the standards of any wealthy family.

But the truth is that Kris raised her children to be successful and from an early age this momager knew what she wanted for her and her children. According to Romper, Kris said in an interview: "I’ve spent many years of my life being pregnant. And for me to raise them and say goodbye to them when they are 18, just isn’t going to work for me. I’ve managed to have the best family dynamic that I can. My girls have all gone through that stage where they push back on their parents, but it’s all about the family dynamic. That’s why I create these relationships and cherish them."

Currently, the family is celebrating their 16th season on the air, and we have had the opportunity to see them grow up on screen, facing all of  life's challenges. That's why, today I would like to talk about 20 details that most people probably did not know about the childhood of the most famous family on the television in our time. Through all their ups and downs, they have remained together, facing everything as a family. So, let's talk about 20 Fascinating Facts About The Kardashians' Childhoods because before fame, not everything was perfect and glamorous.

20 They Had Different Nannies During Their Childhood

It is known that Kris got married at a very early age to Robert Kardashian. She was 17 years old when they started dating and married when she was 22, so the 2 young lovers did not wait to have children, causing Kris to feel uncomfortable with her new role as a mother.

Joni Migdal, Robert's old friend, told Page Six, "(Kris had become) bored and rebellious after giving birth to the children and she would tell Robert, 'I have kids and I have not lived life.'" The couple had to hire nannies to keep an eye on the children and be in charge of the main responsibilities in the house. But that didn't stop Kris from being demanding with her staff. According to Pam Behan in her memoir Malibu Nanny: The True Adventures of the Former Kardashian Nanny, Kris was verbally harsh with the staff in the house. She writes, "When I got home, Kris, who was in the kitchen, looked at the groceries I had just purchased, and let out a torrent of expletives."

19 Robert sr. Came From A Wealthy Family, Which Made Kris's Mother Happy

Zimmerman said, "(Kris) saw a far better financial opportunity with Kardashian than with Cesar", who was the professional golfer Kris was dating back then.

Robert met all the criteria: his family made a generous fortune in the meat packing industry in California, which allowed Robert to grow up in privileged conditions. However, he did not take charge of the family business when he got old enough. Instead, he made his own path as a lawyer. In fact, he bought his first Rolls Royce when he was still in his twenties.

18 Kris Was Most Demanding with Kim

According to Ellen Kardashian, the ex-wife of Robert Kardashian, she found some diaries written by her former husband where he got honest about his life and family. The most noteworthy part was where he said that "Kris was [scolding] (Kim) and... Kim was hysterical."

Ellen told In Touch magazine "These are authentic handwritten journals I have shared, that my late husband Robert Kardashian so carefully wrote during 1989 and 1990 at a most trying and touching time of his life. They are my personal possessions and he left them to me on his passing." But the Kardashians denied the authenticity of the diaries.

Sometimes they even wore matching outfits when they were kids. The girls were so close that they used to sleep in the same room, despite living in a large mansion with enough rooms for all. Kim and Kourtney were inseparable during their childhood.

16 Khloe Was Bullied In High School

She also mentioned an encounter with a teacher in High School who always referred to her as "overweight". The television celebrity wrote in her book "(She) never said I was fat, but I knew she was referring to my size. Words are the weapon we have: they cut the deepest." then she added, "Having someone in your class call you fat, ugly, too tall and so on, you start to think all those things about yourself. And if you're like me, those words are played on repeat inside your head."

In fact, many celebrities are former students of Marymount High School such as Mariska Hargitay, Tatyana Ali, Mia Farrow, Giada De Laurentiis, and Marie Digby. This is the reason why the Kardashians had been linked with celebrities all this time, they basically grew up with the children of famous people in Hollywood.

But the worst moment was probably when Robert Kardashian passed away. Kourtney, who was very attached to her father, had the worst reaction and resented Bruce. In fact, a former nanny told New York Daily News, "Bruce tried to engage with Kourtney and to parent her as a good stepfather would. Kourtney wanted nothing to do with it."

In mathematics, you learn a new subject every single day. So it is actually less beneficial for us to be in public school because we couldn’t keep up, we weren’t learning much. So then I was homeschooled. And every single day, Monday through Friday, one on one with the teacher. So I actually learned a lot more, and it was actually harder being in homeschool which I thought would be the opposite. "

7 Kim Decided Not to Go to College to Pursue Her Dreams

She worked as a stylist for celebrities like Lindsay Lohan and Brandy, and thanks to the celebrity friends she had when she used to study in Marymount High School, Kim became popular among big celebrities.

4 Robert Kardashian Encouraged His Children to Make Their Own Money

Kris had to work from an early age to pay for her things because she came from an economically unprivileged family, while Robert, although he came from a wealthy family, liked to work to get his own things. Both parents had a parenting philosophy focused on hard work and success. Because of this, they motivated their children to have jobs in their teenage years so they could understand the value of money.

According to the website worldation, Kourtney used to work on a movie set as a production assistant. And yes, maybe they didn't have to work in a fast food restaurant but they had to work too.

3 Kim's Famous Friends

As stated earlier, Kim and her sisters studied at Marymount High School, a very exclusive school where wealthy people and some celebrities sent their daughters to study. That's why most of Kim's famous friends are from her childhood, before she was known for her reality show and for building an empire based on her personal brand.

One of her great friends since pre-school was Paris Hilton. The girls grew up in the same neighborhood and both came from wealthy families. In fact, it was Paris who helped Kim with her career as a celebrity stylist.

During an interview on The View, she explained that she regrets her decision saying "He was, I think 18, but from 14 to 18, now looking back I think that’s not a normal thing. I feel like I was almost conned, well not conned, but persuaded because he was older and I felt I wouldn’t be accepted or cool or whatever."

1 After Her Parents Divorced, Kourtney Only wore black for 5 years

And although everyone handled it in different ways, Kourtney was the most rebellious of all. She decided that she would only wear black, as a form of protest. Kourtney only wore black for 5 consecutive years.

According to worldation "After her mother and father separated, Kourtney refused to wear anything other than black clothing for a full five years after the divorce was finalized."
