Fashion powerhouses Kim, Khloe and Kourtney Kardashian have dazzled on "Good Morning America" with their women's designs, but now they're drawing inspiration from the newest additions to their family, going "small" with their latest Kardashian Kollection called Kardashian Kids.

"When I was pregnant with her [Penelope], I said let's do a kids clothing line," Kourtney, 34, explained of how the Kardashians' latest and littlest clothing line came to be. "Kim wasn't even pregnant with North. They were kind of like, 'OK, if you want to take over.' So with this first collection I definitely took charge."

Kourtney's biggest concern for the clothing line "was to make it high-fashion, but affordable," she said, because "they go through it so quickly."

But the new line of baby clothes for girls 0 to 24 months, which launched March 15 at Babies "R" Us, isn't the only fashion-focused Kardashian venture making headlines lately.

Kim and Kanye's highly-publicized cover on the April edition of "Vogue" has generated some backlash in the social media world as many critics seemed to think the couple is simply not worthy of the cover of fashion's most coveted magazine.

However Kourtney has been too preoccupied to even hear about it.

"I haven't seen any reaction," the eldest sister simply said. "I've literally been unpacking."

"But," she continued, "I don't hear about any news. I'm kind of like the last to hear about anything. I posted it on my Instagram and saw these amazing responses and stuff and I'm so happy for her."

"I think it's beautiful."

As for the drastically different family dynamic with Bruce Jenner and matriarch, Kris Kardashian, having split up, Kourtney maintains "Everyone's great," although admitting "there have been a lot of changes lately."

"But it's been good. All positive changes," Kourtney said of what viewers can expect to see on the upcoming season of E!'s "Keeping Up With the Kardashians." "It goes with the territory when we film. There's highs and lows and we show all of those moments and we always have. But everything's kind of turning more positive, I would say."
