Being a mom is what life is about. I hope people realize what the priorities in life should be and know not everything has to be perfect.

Mom always told us to wear pretty, matching underwear.

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

We always say we are a brand for our fans because through social media we're so lucky to see what people are asking us for, what they're looking for, and so we really design what we like but also take our fans in mind.

We spent a lot of time trend forecasting and collaborating on ways to design a fresh line of fashion-forward, affordable luxury.

We do have a two against one rule. If two sisters feel very strongly about a design or trend we want to try, we go for it.

Designing was always something I was interested in. I studied fashion design in high school as well as how to sew.

I would love to design a maternity clothing line. It is so hard to find stylish clothes for pregnant people... I would say 99 percent of the clothes I wore were not maternity because I couldn't find anything I liked.

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.

Kardashian Kollection for Lipsy will have some amazing standout pieces like a full-lace jumper and metallic sequin jackets.

Motherhood has most definitely changed me and my life. It's so crazy how drastic even the small details change - in such an amazing way. Even silly things, like the fact that all of my pictures on my cell phone used to be of me at photo shoots - conceited, I know! - but now every single picture on my phone is of Mason.

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.

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 have oatmeal every morning with whole milk, bananas, and cinnamon, and it's just the best thing ever.

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

My parents got me a sewing machine for Christmas during my senior year of high school. I made three pieces of clothing and had a fashion show at the end of the year, where we had to wear the clothes that we made. I took it to a whole new level; I made all my friends clothes.

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.
