The first trailer for The Baby-Sitters Club season 2 is here, and it hints at some big changes in store for the girls.

Kristy Thomas, Mary-Anne Spier, Claudia Kishi, Stacey McGill, and Dawn Schafer are back in action in the first trailer for The Baby-Sitters Club season 2 and this time, they’re bringing some new friends along for the ride.

A new season brings with it some big changes for the BSC, where business is clearly buzzing— so much so that the girls are gearing up to welcome two new sitters in Mallory Pike and Jessi Ramsey.

But growing their business isn’t the only thing the girls will have on their plate come season two. In addition to navigating the trials and tribulations of baby-sitting, they’re also trying to deal with some huge change.

For Mary-Anne, that means pursuing her budding romance with Logan from camp, in addition to navigating her new life at home now that Dawn and her mom have moved in with her and her Dad. Similarly, Kristy’s also struggling to acclimate to her new blended family situation, which might soon be growing by one.

On the Claudia front, it seems like something could be going on with Mimi, meanwhile a scene with Stacey hints at some struggles with her diabetes that could put a wrench in some big plans.
