Kim definitely has her hands full now that she welcomed her second child , 2-month-old Saint West, with husband Kanye West -- even blogging about her struggle on her app.
"I'm up at 4 a.m., pumping and delirious, hiding in my daughter's closet because if she sees I snuck out of her bed, she will start to cry AND I think she gave me a cold so I figure no better time to [write] than now!" she recently wrote.
"I never really understood that until now," the 35-year-old reality star 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?!' Of course, I expected it to be different but, wow, it really is so hard!"
