Kim Kardashian Says She "Gets No Sleep" Now That She Has Two Kids

The 35-year-old opens up about life with North and Saint West in a new blog post on her website and reveals that having a 2-year-old and a newborn is much harder than she ever imagined.

The "Keeping Up With The Kardashians" star, who welcomed her son in December, said she wrote her post while pumping at 4 a.m., hiding in North's closet so the toddler wouldn't hear her leave the room and start crying.

"My mom would always say, about having kids: 'One is like one, and two are like twenty. I never really understood that until now," she wrote.

"It seemed like every time Kanye and I would go out, we would see couples-or really anybody that had kids-and everyone would say, 'Wait until you have two.' Like it's the end of the world," she continued. "I remember Kanye and I would be like, 'WTF are they talking about? Will our lives be the same? Are we going to be OK?!'"

Once the reality star gave birth to Saint, she realized that having a baby this time around was much different now that she has to juggle time with her daughter.

"Of course, I expected it to be different but, wow, it really is so hard! When I had North, all I did was feed and sleep," she said. "This time around, I get no sleep. Every waking second that I'm not with the baby, I'm with North. I actually think the harder parts aren't with the newborn but with the toddler! I feel like I go into overdrive to give my daughter attention and make her feel loved."

Luckily, the brunette beauty has had plenty of help juggling her family thanks to husband Kanye West, who spends special time with North and Kourtney Kardashian's daughter Penelope, who gives tons of advice to her cousin!

"Kanye is super helpful, taking North out to dinners (just them!), and I'm so lucky North looks up to Penelope a lot," she revealed. "She also has a baby brother so she gives North the best advice. I have the cutest video of P giving North a heart to heart about being a good big sister."
