Kailyn Lowry Pregnant With Third Child

In her just-released announcement, the 'Teen Mom 2' cast member explained why she wanted another offspring

Kailyn Lowry is about to celebrate a milestone event: The Teen Mom 2 cast member is expecting her third child.

"I am pregnant," Isaac and Lincoln’s mama shared on her website, along with an image of a sonogram.

"I’m sad that I should have known that people in my life would sell me out before I was ready," she continued. "Like any normal person, I want it to be a happy time. I wanted this to be a private time so I could be excited while not getting chased by paparazzi and bothered with crazy headlines. Please know this was a choice I made; I already know some won’t agree, but I’ve been showered with support by the ones I love since I found out."

Kail elaborated on her decision to wait to reveal the life-changing news. "I’ve had a lot of health complications leading up to this pregnancy, and I was not ready to release such private information on my own just yet being that I am so high-risk with this pregnancy," she stated. "I didn’t want to announce just to have another miscarriage and suffer through another grief."

"I was filmed on the show saying I didn’t want any more kids, but I’m pregnant again," she wrote. "I know so many will have comments on this, but here’s the thing -- I didn’t want to bring another child into a failing marriage. Shortly after I started having complications, the option of having more kids was almost taken away from me. When I started thinking long and hard, I knew I wanted more. This was the choice I made. This is the baby I thought I wasn’t sure if I could have. I know this isn’t an ideal situation, but I know everything will be okay. And like I say in my book -- with a little bit of hustle and heart, I can and I will survive anything. Having another child is something I am so happy about, and I just can’t wait. My boys are so excited, those who love me are so excited, and I hope that everyone can just be happy for me during this time."

As fans of the long-running series know, Kail's firstborn Isaac made his grand debut during 16 and Pregnant back in 2010, and two-year-old Lincoln was born during the fifth installment of the reality program. We'll never forget Isaac adorably declaring, "Look! He's a baby!" and stating that the newborn’s hair was “disgusting” (relive it in the sentimental clip below) when he met his sibling for the first time. Such sweet memories -- and there’s more to come for Kail’s boys in the not-so-distant future! Wonder what the adorable duo will declare when they bond with this munchkin (Kail isn't finding out the peanut's gender until the summer!).
