The Divergent star, who welcomed son Bear back on Dec. 7, says she was too busy after giving birth to overly worry about losing the pregnancy weight.
"To be honest with you, after having a baby you end up being so busy with the baby and the nursing," the Oscar winner told E! News exclusively at the Divergent movie junket. "And I have two other children as well obviously, so there's so much going on that the difficulty I find is remembering that you have to eat. Because when you're nursing you really have to eat, otherwise you don't produce anything that's going to feed your child. So nursing's a great excuse to eat heaps. That's what I've been doing."
Adding to Winslet's busy schedule was the fact that she had to get back to the Divergent set just weeks after giving birth!
"When Bear, my son, was 6 weeks old, they said, ‘We need you. We have a few days of reshoots to do.' And I said, 'Are you high?!' Like, how am I going to do this? But somehow you do. You just make it work."
Winslet said she would "feed and shoot and nurse" on rotation while working on set. She gushed, "There's actually something empowering about going, ‘Hey, I can do this! I can do all of this!'"
But as for squeezing her post-baby body back in to her Divergent costumes? "Getting into the costume again was a little bit like squeezing a sausage into a thimble!" she joked. "I had just had a baby! It just doesn't feel right. Your body is very soft."
