After nursing Dolly and Charlie for six months, Romijn swapped places with husband Jerry O'Connell so she could return to work on the new witch-themed drama.
And her relationship with her babies is better than ever.
The actress tells Starpulse.com, "I was with them right up until they were six months which is when we started shooting, and I felt like they kind of took me for granted a little bit, like Jerry'd walk in, they'd be like, 'Ahhh.' But then they never even noticed that it was me with them the whole time. I was a milk machine. I felt like that's all I was to them, just this walking milk machine.
"Now that I'm not there as many hours during the day, they're pretty clingy and I have to say I love it. It's the best feeling in the world."
