Khloe Kardashian: 'It's the perfect time for Kourtney to have baby'

Khloe Kardashian has said that she thinks the timing is right for her sister Kourtney Kardashian to have another baby.

Kourtney announced last month that she and long-time boyfriend Scott Disick are expecting their second child in 2012, the same week she launched a 'Mommy Blog' on her official website to offer parenting tips.

Talking to MTV News, Khloe said that Kourtney's son Mason is at the perfect age to become a big brother to a new sibling.

"[Kourtney's] good. She's a little more nauseous this time around, which I feel bad about, but she's great, and it's so exciting," Khloe said.

"She doesn't have any belly yet, of course - only her - but Mason's second birthday is coming up [Wednesday], so it's crazy. But I think it's the perfect time for her to add another baby. Mason's old enough."

Earlier this month, the sisters shot down rumors that Kourtney would give her baby to Khloe, who has been struggling to conceive with husband Lamar Odom.
