This is the second child for the 23-year-old reality star. She also has a six-year-old son named Bentley with ex Ryan Edwards. Ryan first appeared with Maci on 16 and Pregnant, and the two split after the first season of Teen Mom.

Bentley was definitely excited to get a little sibling. According to grandma Sharon Bookout, the now-big brother said, "You can kiss her, she’s really soft!" How adorable is that?!
