Maci Bookout's Son And Daughter = The Cutest Sibling Duo EVER

Bentley and Jayde sharing a cuddle will make your heart melt.

Maci Bookout recently expressed her desire for her children Bentley and Jayde to have a close relationship -- and it certainly appears that the "Teen Mom OG" kiddos are well on their way to building a very special sibling bond.

The author -- who welcomed her mini-me with beau Taylor McKinney at the end of May -- posted the scrumptious Instagram snapshot below of her son holding her teeny-weeny daughter. The perfect caption accompanied the tender moment: an emoji of the world.

The affectionate six-year-old is making perfect eye contact with his mama and giving his sister a sweet nuzzle, while Baby J is cuddling up close to her fantastic big brother. And while we can't see the tiny tot's beautiful face (but those dark, thick locks and that polka-dot ensemble!), it appears that the sweet pea is right at home in Benny's loving arms. More family photos, please.
