The eldest Kardashian sister has some breastfeeding tips for mothers out there. Kourtney Kardashian just gave birth to her third child, Reign Aston, three months ago and breastfeeding is a daily task Kourtney attends to as she cares for her new born son. Kourtney and boyfriend, Scott Disick, are parents to two older kids-Penelope 2 ½ and Mason, 5.

In an article in People magazine, Kourtney revealed that she still manages to breastfeed little Reign even while on a trip. After spending the day at The Marquee Day Club in Las Vegas, the "Keeping Up with the Kardashians" reality star pumped milk with the aid of a breast feeding-friendly bra. Kourtney posted the photo of her pumping out breast milk on her Instagram account.

The star captioned the photo with this message: "After the show it's the after party."

Kourtney revealed to People that she and her girlfriends had planned the fast trip to Vegas to have fun and bond together. She said, "We keep calling ourselves the mom-kabobs.  It's all my close girlfriends. It's the fastest Vegas trip ever."

In an episode in "Kourtney & Khloé Take Miami", Scott Disick's partner also used the same Simple Wishes D*Lite Hands Free Pumping Bra to pump out breast milk after an evening of partying.

Meanwhile, Scott is currently doing time in a rehab facility in Costa Rica. Kourtney's brother-in-law, Kanye West, allegedly thought Scott is not taking fatherhood seriously, as Hollywood Life reported. An insider revealed to Hollywood Life that:

"Kanye's not really a big fan of Scott as a father. He thinks Scott takes fatherhood for granted. He also thinks Scott makes stupid decisions and doesn't consider himself, [Kourtney] or his children when he should. Kanye's furious about Scott's latest acts of stupidity and he told Kim [Kardashian] that she should tell Kourtney not let Scott see his children until he gets his act together."

In an E! Online article, though, Kourtney announced that she was proud on her boyfriend's progress in rehab. Kourtney revealed that:

"He's [Scott] doing well, and, you know, really focusing on himself and working on himself. He's made a lot of progress, so I'm proud of him."

The new father was scheduled to come home on Monday. However, Scott had very good experiences in the rehabilitation center overseas that he would stay for a few more days.

Scott is set to host a party in Las Vegas' 10 a.k. on Friday.
