While captioning the image with a simple blue heart emoji, the proud mom also posted a photo of husband Kanye West toting their nearly 4-year-old daughter North.
“My baby boo,” she captioned the image of the daddy-daughter duo.
The reality star, 36, recently opened up about her adorable kiddos.
“He’s my twin,” she gushed of her son. “He’s literally my twin personality. He’s so sweet. And he’s just such a good good boy. Just such a good person.”
Meanwhile, it sounds like her daughter takes after her husband.
“She’s really really smart, actually. She knows how to outsmart us — or she thinks she does. But she is Kanye’s twin,” the KUWTK star said of her elder child. “Same personality, says the same wild things. Those two…”
Is there any sibling rivalry in their household?
“North just beats him up all day long… she’s just awful,” admitted the mom-of-two. “She is so jealous, and I thought it was a phase — it’s not going away. She just says boys aren’t allowed in her room. Like, when she’s gone at school, I’m like, ‘It’s time let’s go in her room! Do whatever you want — go crazy!’ ”
In fact, the reality star had to come up with a creative solution while breastfeeding her baby boy.
“When I was breastfeeding him, [North] was so jealous I had to get a little milk box and put it in the other bra with a straw so she would drink and he would drink,” she revealed. “She’s so jealous. It’s crazy. The things you do.”
