[13] In March 2020, Sophie Grace, Malia Baker, Momona Tamada, Shay Rudolph and Xochitl Gomez joined the cast of the series.

[14] On March 18, 2021, it was reported that Kyndra Sanchez joined the cast as Dawn Schafer, replacing Gomez due to scheduling conflicts with Doctor Strange in the Multiverse of Madness.

[15][16] Summers told Refinery29, "Most of the characters' [looks] were purchased from places these girls would shop in real life: Zara, H&M, American Eagle, Gap, Urban Outfitters, Aritzia, Topshop, Kate Spade, Alice + Olivia, Anthropologie, Nordstrom .

The website's critical consensus reads, "Sweet, sincere, and full of hope, The Baby-Sitters Club's grounded approach honors its source material while updating the story for a new generation.

"[23] Rebecca Onion of Slate said, "The new show is indeed adorable—the multiracial group of suburban middle schoolers earnestly booking gigs from their perch in Claudia Kishi's colorful bedroom is just as plucky and kind as ever .

The new show has gotten plaudits for its diverse cast and plotlines, but in many important ways, the whole idea is a pure fantasy: of suburban community, of gentle coming-of-age, of meaningful work that teaches responsibility and pays just enough for fancy new paintbrushes.

Petrana Radulovic of Polygon said, "Like their book counterparts, all the girls in The Baby-Sitters Club are more in-depth than their one-word trope descriptor (tomboy, goody two-shoes, artsy kid, prep, hippie) implies, thanks in part to the skillful performances from the young actresses.

As spunky, outspoken Kristy, Sophie Grace adds nuance to her bossy, bratty attitude, grounding what could be an over-the-top performance with some tender moments.

Momona Tamada, of To All the Boys I've Loved Before fame, captures Claudia's quirkiness and energy, but not without pangs of isolation because she feels her family will never understand her.

"[26] Hank Stuever, writing for The Washington Post, noted "the show's remarkably talented cast of young actresses, all of whom either never learned the kidz-show style of overacting ('schmacting,' we sometimes call it), or were never afflicted with it to begin with.

The girls buy a landline phone on Etsy, hit up local parents with targeted Instagram ads, and make comments like, 'Art shouldn't be only the province of the privileged!'

The website's critics consensus states, "The Baby-Sitters Club returns with a strong second season that explores new issues with care and gives its charming cast plenty of room to shine.
