Oh, baby! Kailyn Lowry gave birth to her newborn son earlier this month, making her a mom-of-three boys. Over the weekend, the Teen Mom 2 star decided to celebrate the arrival of the newest addition to her family by taking new photos as a family of four — and she shared a new breastfeeding pic featuring Baby Lo!

Kail almost immediately started to plan her family photos — just five days after giving birth, she was already ordering outfits for her three sons. She decided to go with a mismatched theme for her seven-year-old son Isaac (whom she shares with her ex-boyfriend Jo Rivera) and three-year-old son Lincoln (whom she shares with her ex-husband Javi Marroquin) — and they both look so adorable. Watch the video below to see behind-the-scenes photos from their family picture day!

Even though she was open about her concern with raising her newborn son on her own— who has been nicknamed Baby Lo until Kail announces his official name — it looks like she got what she wished for and her baby daddy Chris Lopez is finally coming around. He was with Kail when she brought their son home from the hospital and she recently said that he's been slowly stepping up as a father for Baby Lo and she recently defended his progress.

“Every child deserves their dad. I’m hopeful. I’m positive he’ll be around," she told Radar Online. "I think he has been as supportive as he can. He does the best to his ability even though it doesn’t necessarily meet the standards of what everyone else expects of him. I think people need to keep that in mind.”
