So sweet! Jen Arnold of TLC’s The Little Couple series shared a cute photo of her daughter via Instagram on April 9, and Amy Roloff of Little People, Big World commented on it. Did they just become best friends?

“Can’t believe my little girl lost her second tooth! #toothfairy #cutetoothless #littlecouple,” Jen, 45, captioned the most adorable photo of her 7-year-old daughter. Amy, 54, then replied, “They’re growing up so fast. Oh, the memories of my own at this age.” Amy is the mother of Zach, Jeremy, Molly and Jacob Roloff, but they’re all grown up and off living their own lives these days.

Jen then responded to Amy’s comment, “awe! I know, it’s happening way too fast. Hope you are well and getting to enjoy your adorable grandbabies!” Jen’s kids are little enough that she doesn’t have grandkids to worry about yet, but Amy has two — Jackson and Ember Roloff, a.k.a. two of the cutest kids in existence, if you ask us.

Amy wasn’t the only one who waxed nostalgic in Jen’s comments. “She’s come a long way,” one fan commented. Another wrote, “She’s so pretty, can’t believe [losing] her teeth. I remember when [you] were waiting to get her, so happy for all of [you] what a beautiful family.”

New episodes of The Little Couple haven’t been on TLC since December, and watching Jen’s social media accounts is one way fans can keep up with the lives of the Arnold family while they await a new season. She posts pretty regularly but seeing Amy comment on Jen’s photo of Zoey was one of the most exciting developments for fans of both The Little Couple and Little People, Big World in a long while. “OMG two of my favorite people on TV. Hopefully, Zoey and [Will] can meet Jackson, that will be the cutest,” one follower wrote. We agree! Make it happen, producers.
