The actress shared a series of stunning images from her babymoon in Hawaii on Instagram in April.
She also celebrated with an outdoor boho-chic baby shower in late May, at the Beverly Hills home of director and celebrity stylist Sophia Banks. At the bash, guests, including Parenthood costars Mae Whitman and Lauren Graham, sipped on mimosas, noshed on tacos and cake and made their own flower crowns.
“Erika was so happy and loved being welcomed into motherhood by her friends … so many incredible mothers and women,” a source told PEOPLE of the shower.
“It’s still rather surreal,” Christensen told PEOPLE in April of being pregnant. “She’s a little kick boxer in there — she’s big and moving and communicating as far as reacting to music that we play and stuff like that.”
