Sisterly spat! Now that Khloé Kardashian has officially announced her pregnancy, the Keeping Up With the Kardashians stars is no longer keeping any secrets from her fans. Khloé stopped by Jimmy Kimmel Live and she dished about all of the details about her pregnancy so far now that she’s six months pregnant with her first child with boyfriend Tristan Thompson — and she revealed that she’s getting a ton of unsolicited mom advice and it’s causing fights between her and her older sister Kourtney Kardashian!

“A lot of it is, you know, unwanted,” the 33-year-old said about all of the advice she’s been getting from her family members. “I don’t know if it’s the worst, but Kourtney gives a lot of advice and I think it’s so sweet, but I don’t want to do some of that stuff, it’s like, ‘You can never have a plastic toy ever.’ But if someone buys f–king blocks, I’m allowed to have blocks! Let me experience things.”

Kourtney was the first of the Kardashian sisters to become a mom — she gave birth to her first child, Mason Disick, in 2009 — and now that she’s a mom-of-three, it seems like she has enough mommy experience under her belt to give out some good advice. But Kourt is “crazy,” according to her sister, and she has some strict rules for her kiddos, like no plastic toys because of the toxic chemicals can be harmful to kids if they put the toys in their mouths.

“We’ve been fighting a lot lately,” Khloé continued. “We never fight — she got pissed because I wanted to put a tv in the nursery!”

This isn’t the first time Khloé has complained about her sister’s unsolicited advice about parenting, and she revealed in an interview with Entertainment Tonight that she just wants to figure out motherhood on her own. “Like, I love Kourtney, but…I’m going to figure it all out, I promise you,” she said. “We’re all going to learn.”
