Kardashians may love the limelight, but former Fit Pregnancy cover girl Kourtney Kardashian has been coy about presenting her latest baby with partner Scott Disick to the world ... until now.

To date, the only part of 3-month-old Reign Aston the public had seen was his sweet little hand following his birth in December.

But Mama Kourtney, 35, has now decided to introduce her new little guy over Instagram, in a sweet pic showing him dressed all in white and sporting just the teeniest cheeky smile.

"My little turtle dove angel baby Reign Aston Disick," she cooed in the caption.

Little Reign Aston is Kardashian's third child with Disick after son Mason Dash, 5, and daughter Penelope Scotland, 2 1/2, making this Kardashian micro-clan a party of five.

Kardashian is known for putting family first. In her down-to-earth interview in the December/January issue of Fit Pregnancy, the reality star spoke out about maintaining a positive body image during pregnancy and putting her kids first.

"I feel comfortable with how I look and feel," she said. "I find a pregnancy body to be beautiful and an incredible reminder of what a woman's body is made to do."

When asked about how she juggles the spotlight with being a mom, she had a quick comeback: "My time is limited and I'd rather be spending it with my kids."

Kardashian proved her ability to shift from the party lifestyle to mom duty in an Instagram snap from last month showing her working the breast pump after a Las Vegas party.

We have to say we're pretty impressed by this Kardashian. She somehow manages to keep it all in perspective, even waiting three months to show the world her new baby boy. We salute you, K. Keep up the good work! And as for you, Reign Aston, never stop being so GOSH DARN ADORABLE! *Sigh*
