JoAnna Garcia Swisher is officially back on diaper duty. The Astronaut Wives Club star has welcomed her second child with husband Nick Swisher and shared the sweetest photo on Instagram to celebrate the news of their baby girl.

"So excited to introduce you to our tiniest princess, Sailor Stevie. She has stolen our hearts and our family feels complete, Nick, Jo, & Big Sister Emme #SSS," she captioned the photo, which shows the smiling mom and dad cuddling their little one, who is wrapped in a blanket, rocking a knit cap and sucking her thumb.

The couple first announced the news of JoAnna's pregnancy back in February with an adorable collage of her, Nick and their 3-year-old daughter Emme that included a snap of Emme smiling and standing in a crib that had an "eviction notice" sign on it. "Nick, Emme, and I are so excited to finally share this news...," the actress, 36, captioned the photo, adding a baby, baby bottle and other baby-themed emoticons.

JoAnna and Nick welcomed Emme in May 2013 after tying the knot in 2010. Congrats to the Swisher family!
