"I'm about 2 months into breastfeeding and I'm not gonna lie — it can be time-consuming," Kardashian, 35, explained. "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, LOL! 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 of her, and now she is my little helper."
Kardashian and her husband, Kanye West, welcomed North's younger brother last month. The couple — who have yet to reveal Saint's face — are still living at Kris Jenner's Calabasas, California, estate while their home is under construction.
"I feel super lucky that breastfeeding is easy for me and I produce a lot of milk — so much that I've taken over my mom's freezer with tons of milk!" Kardashian added.
The Keeping Up With the Kardashians star did have a tough time breastfeeding at first — until she used a nipple shield.
"I find the baby feeds better, and it allows me to never get irritated nipples or anything because they're protected by the shield," she wrote. "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."
Kardashian — who tweeted earlier this week that she's "delirious" from 4 a.m. feedings — also revealed whether she'd ever breastfeed in public.
"Now that I'm a mom, 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. 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," she wrote. "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. I think it's such a natural experience and I'm not shy about that."
She doesn't mind breastfeeding photos, either. "I know so many people get backlash for posting breastfeeding pics, but I don't mind them!" she wrote. "I know people have their opinions on how others should live their lives and I try not to be judgmental anymore—this is simply just my opinion."
