America Ferrera is set to become a first-time mom this year, and she recently revealed that her Sisterhood of the Traveling Pants costars Amber Tamblyn, Blake Lively, and Alexis Bledel are a source of some pretty amazing new-mom advice.

“They’re a go-to for me,” Ferrera told Us Weekly, admitting she texts them with her questions. “Everything from trying to wrap my mind around the actual birth itself and talking about what their experiences were and what to prepare for.”

It comes as no surprise that Ferrera’s Sisterhood costars are a source of support and comfort for the mom-to-be. Lively and husband Ryan Reynolds share two daughters, Ines and James; Tamblyn and husband David Cross have a one-year-old daughter, Marlow; and Bledel welcomed her first son with husband Vincent Kartheiser in 2015. The girls have maintained an off-screen bond since first meeting on the 2005 film — even recently revealing that they schedule play dates for the kids — and Ferrera said that their perspectives on everything from the day-to-day stuff to the bigger picture have been invaluable.

“I think one of the things, for every woman I’ve spoken to, is once you’ve been through it — it’s like, let go of your expectations because it’s going to be what it’s going to be,” Ferrera told Us Weekly. “I’m lucky that I have so many amazing women around me who have had children and are in very similar positions as me — are working and have to get back to work,” she continued. “Having their support has been everything.”

Ferrera and her husband Ryan Piers Williams excitedly announced her pregnancy on New Year’s Eve, but have not revealed details on a due date.
