My stepdad is Bruce Jenner, the Olympian. The first time he came over was like a blind date, and we had show and tell. He took out the gold medal for me and my sisters, and we were like, 'So? Who the hell are you?'

I loved dressing for my pregnant body. A pregnant woman's body is so beautiful. Towards the end, it does get harder, and then it became all about flats and comfortable maxi dresses.

Sometimes I think, 'Why should I work out when I can spend time with my kids?' I feel guilty doing something for me.

I love Audrey Hepburn.

I think it's important to talk to my sisters when I have a big decision to make.

Now that I have a daughter, I've been thinking about how I'll define beauty to her. I watched a video of Kendall when she was three, and she was putting on makeup. I don't know how I feel about that. But my daughter already watches me do it. When do you let them start wearing it? I don't know yet.

I think with boys... it's all about shoes. I've seen so many little boys, and their outfits are so cute, and then their moms put kind of dorky shoes on them.

My mom and both of my grandmothers have always been into fashion, so it's been around us our whole lives.

I think I forget every time - you give birth, and you want your stomach to be flat again. It does take a lot of work, but I usually start slowly by going on walks with the baby.

I've always loved children's clothes - my grandmother actually owned a children's boutique in La Jolla, CA, for 30 years. I grew up visiting her and working in her store, and then my mom and I had a children's boutique together for five or six years.

I remember when I first found out I was having a boy, I became obsessed with buying boys' clothes. Then came my daughter, and I was obsessed with buying girls' clothes. Everything looks 10 million times cuter when it's teeny-tiny.

I wouldn't say I'm strict. I love to communicate with my kids, and I constantly check in and try to talk things through instead.

My entire life changed when I became a mother - my priorities, my understanding, appreciation of life, and my relationship with God.

Women always ask me how to get back in shape after having a baby. I always say, 'Know when's the right time for your workout and commit to doing it.'

I was surprised that everyone calls it 'morning sickness,' because it lasted all day. For me, it was even worse at night. During my first two pregnancies, I felt so nauseous all day that I could only eat plain toast and bland foods - no proteins.

I love being pregnant in general.

I find a pregnant body to be beautiful and an incredible reminder of what a woman's body is made to do.

Before Christmas, I host a party for our kids and all their friends. We love to make a mess while decorating gingerbread houses.

Since we started putting together our makeup collection, Kardashian Beauty, I've been extra invested in our list of no-no ingredients. It's an ingredients black list that we don't allow into the products - no parabens, no sulfates.

When I do my own makeup, I always start with Laura Mercier Tinted Moisturizer.

I've been applying makeup long enough to feel good doing it on my own, but I cannot do my hair to save my life. When left to my own devices, if I have to go to an event, I do a slicked bun. Otherwise, I just try to wear a hat, put it in a ponytail, or do a side braid - something easy.

We're definitely honest with each other... if your sisters can't tell you that you look ridiculous, who can?

Nothing comes before my children. I find that putting everything else in order of importance also helps to get everything done.

First dates are so awkward and annoying. I think a casual and fun first date with friends is much more fun than a one-on-one typical first date.

I don't think fame is that important to me.

We've always wanted to do a clothing line, and I personally love doing stuff with my sisters; I think it makes the whole process that much better.

I nursed Mason for 14 months and Penelope for 16, and I loved it. It was built-in time that the two of us could share alone every day. I didn't have any goals or expectations.

After Mason was born, I'd feel guilty doing anything that wasn't related to work.

After my daughter was born, I made a promise to myself to live in the moment.

I am obsessed with my sisters. Being the oldest, I probably just have that in me. But I also think I am the youngest sometimes. We all have moments when we are the maternal one of the group.

I feel that if I'm going through something, I'm sure someone else is, too.

I love and appreciate the bonding time with Mason. Nursing is surprisingly one of my favorite things.

I'm learning to trust other people to do things. My time is limited, and I'd rather be spending it with my kids.

The first thing I do when I'm shopping is touch everything to see if it's itchy. I remember my mom used to put me in the itchiest clothes ever, and I was traumatized by it, so I won't wear anything itchy now.

I actually hate when people open my gifts, and I hate opening gifts in front of people.

I know my mom always likes to give the over-the-top 'wow' pieces at baby showers.

Sometimes, it's hard to separate manager mode from mom mode. I think, as our manager, my mom will get more emotional about situations than she would if she was just our manager.

My mom fed us a lot of processed food when we were kids, like chicken fingers, grilled cheese sandwiches and quesadillas. I make those treats for my family, too, but I use organic cheeses and whole wheat bread and tortillas.

My kids' doctor will quickly answer any email, even if it's 11:00 at night. That's important to me.

One of my favorite things to do is go running early in the morning when everyone in my house is still sleeping. I throw on my iPod, and it's, like, my time.

I'm not a dating person.

I just got out of a nine-year relationship. I think the last thing I probably need is anybody in my life.

It is still crazy to me that I have two boys born on the same exact day. I really tried to not have it happen, so they could each have their day, but there was no way around it.

Mom always told us to wear pretty, matching underwear.

I don't want to judge, but I've also met women who think it's cool to be out or away from their baby, and I don't get that.

It was my first time taking a taxi with Mason. I had to tell the driver to wait because I had to get the stroller out of the car.

My mom bought me this amazing baby-food maker, the Beaba. I steam and puree fruits and vegetables, and they last for, like, four days.

Unless someone has walked in your shoes, you really can't judge. Everyone needs to make the best choice for their life.

I think motherhood is just about instinct.

When my younger sisters were born, I was in high school and college. I was at my mom's all the time but never changed them or fed them.
