The Mad Men star and her artist husband Matthew Heller became parents to Saskia, a sister for their son Akiva, last month (Feb12).
Dudek has opened up about her day-long labour in a post on her blog, revealing doctors wanted her to undergo a Caesarean section, but she insisted on a natural birth.
She adds, ""I did push Saskia out, and it was one of the weirdest and most intense things I could ever imagine. I reached down and put my hands under two tiny armpits and pulled her to me, huge cheeks bright red, her little eyes darting about, my sweet love. Welcome to the world Saskia.""
