The 35-year-old mother of two also shares her best advice for fellow nursing moms.

Kim Kardashian is getting candid about breastfeeding.

In a new post on her app, Kim opens up about the one surprising challenge she has faced in nursing her 2-month-old son, Saint.

"For some reason, North hates when I feed the baby, and she lays on my lap so Saint can't be right in front of me to eat," Kim shares. "I've started to include her. Sometimes I will pump and have her feed him the bottle. That totally worked! She loved helping me, as opposed to my attention being off her, and now she is my little helper."

Kim is also weighing in on the oft-debated topic of public breastfeeding, revealing why she isn't comfortable doing so herself.

"I say, whatever makes you comfortable goes. I still personally wouldn't breastfeed at a restaurant with a bunch of people I didn't know staring at me," she writes. "I've seen this before and remember tweeting how shocked I was. Now that I'm a mom, I'm not that shocked, especially if you have a few kids and can't leave to breastfeed one kid in the bathroom while leaving the others at the table. But I still personally wouldn't do it, unless it was an emergency situation and I was fully covered.

"I would, however, breastfeed in front of my girlfriends," she continues. "I think it's such a natural experience and I'm not shy about that. I know so many people get backlash for posting breastfeeding pics, but I don't mind them!"

The 35-year-old reality star says she feels "super lucky" that breastfeeding is "easy" for her, and she's offering up her best advice to fellow nursing moms.

"I use a nipple shield most of the time when I feed," she says. "I find the baby feeds better, and it allows me to never get irritated nipples or anything because they're protected by the shield. The hospital suggested shields to me, since at the beginning I found nursing super painful and difficult, so I took some home and never looked back."

Kim is hardly the first celeb to get candid about breastfeeding recently. Notably, actress Alyssa Milano has been vocal about her decision to publicly breastfeed and told ET, "I think people are more comfortable sexualizing breasts than relating them to what they were made for, which is feeding another human."
