The moment we've been waiting for is finally upon us! During next week's episode of Teen Mom 2, Chelsea Houska's daughter, Aubree, will come face-to-face with her new baby sister, Paislee Mae! This adorable bambino was welcomed into the world back in September, and her parents, Adam Lind and Taylor Halbur, are all about Paislee having a rock-solid relationship with her half sister.

Sure, Chelsea isn't thrilled about Aubree spending time with Adam and his new family, but this sneak peek clip from next week's all-new episode makes it clear that Aubs is over the moon with happiness about being a big sister. In what might be the cutest moment in Teen Mom 2 history, Aubree carefully holds Paislee and says, "I'm your big sister." Then she serves up a series of adorable musings, including "Can we put her in the stroller when we go swimming?" and "She's got one eye!"

We can't even handle the cuteness. And by the way, Adam seems like a pretty devoted father — at least judging from this clip. Check out the tender way he helps Paislee with her pacifier, and the sweet way he includes Aubree in their hang session. Clearly this dude has parenting on the brain, as is evidenced from his amazing t-shirt "Tattooed Parent."

Do you think Aubree and Paislee will grow up to be super close, or will the animosity between Chelsea and Adam prevent them from being besties? Weigh in below!
