Maggie Gyllenhaal was on Chelsea Lately yesterday and she was talking about breastfeeding her daughter on the set of White House Down. When they were filming and it was time to feed her kid, she would ask the AD if she could go ahead and do so. Sometimes he would be willing, but other times he wouldn’t be. So when it was one of those times, she would get his attention by squeezing her boob twice. Once he saw that, he let her do what she needed to do.
So I think by sharing this story, she has inadvertently come up with the new international sign for breastfeeding!
