Jamie-Lynn Sigler and JoAnna Garcia
First-time moms Sigler, Garcia, and Jenna Dewan Tatum have all traded parenting tips in the time since giving birth in 2013. "It'll be so fun to do mommy groups and things together and use each other's experiences to learn." Sigler, mom to son Beau, predicts that he'll have quite a bit of face time with her friends' daughters Emerson and Everly.
