As America Ferrera is getting ready [2] for the arrival of her first child with husband Ryan Piers Williams [3], she's turning to former Sisterhood of the Traveling Pants costars Amber Tamblyn, Blake Lively, and Alexis Bledel for parenting advice [4].

"Of course, my Sisterhood gang," America told Us at The North Face's Move Mountains launch [5]. "They're a go-to for me. Just one text message away, and I ask them a million questions all the time [6]."

Blake, Amber, and Alexis are all mothers to toddlers [7], so America is getting first-hand advice and loving it.

"Everything from trying to wrap my mind around the actual birth itself and talking about what their experiences were and what to prepare for. 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," she said. "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. Having their support has been everything."

Amber has previously mentioned that the four of them already have play dates [8], and joked about passing on a pair of magical jeans [9] just like they did in the movie. "We'll have to get the tiniest pants you've ever seen in your whole life."
