Amanda Peet Shares Her Unusual Breastfeeding Routine

Amanda Peet uses cabbage in an unusual way.

Amanda Peet is spilling a breastfeeding secret that involves produce.

On The Ellen DeGeneres show on Wednesday, Ellen asked the actress about a picture of her with cabbage on her breasts.

The old wives tale is one that Amanda is following after breastfeeding her baby boy Henry who she welcomed Dec. 6 with husband David Benioff.

"Some people get painful engorgement and you can put cabbage leaves on your boobs and it stops the milk," she explained to Ellen.

And yet, her trick doesn't really work. "It's just an excuse to put cabbage on your breasts," Ellen said in response, causing Amanda to laugh.
