As an Option if you're not near the Nursing Mothers Lounge and need to breastpump/breastfeed, Travelers Aid whose main office is in Terminal 2 next to the 'Kids on the Fly' exhibit will happily welcome breastfeeding mothers and offer up a private, comfortable space to breastfeed. Their hours are as follows:
Some moms call it Nursing Room, Breastfeeding Room, Lactation Station, and others Lactation Room. MomsPumpHere Nursing Room Locator (also Airport Lactation Rooms Locator) is a breastfeeding room finder, nursing room finder, lactation station locator, and lactation room finder. We find moms nice, quiet places to breastfeed or breastpump no matter what they call it. Lactation rooms also help moms relieve oversupply of breast milk which can cause mastitis while breastfeeding.
