She's not happy now that she has to share the spotlight!

Kim Kardashian has been in hiding since giving birth to son Saint this past December, but the reality star just shared a few new details about life with her baby boy, and it sounds like big sis Nori is having a hard time adjusting!

"I'm about 2 months into breastfeeding and I'm not gonna lie — it can be time-consuming. 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," she wrote in a new blog post.

Kimmy K also divulged that she uses a "nipple shield" to avoid breastfeeding being super painful. TMI!

"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. 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!" she bragged.

Just because the brunette bombshell is breastfeeding up a storm doesn't mean she's comfortable doing it in public, though!

"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. 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 confessed.

My how her life has changed these past few years!
