Terminal B – The women’s rooms have a separate baby area with a bench for nursing and a changing table and an accordian-style pull-across door for privacy.
The airport also has a family room, which is a very open space. It has lots of rocking chairs, a place for toddlers to play, a kinetic scuplture to watch, and large windows looking out onto the tarmac. It may not be good for nursing a baby who needs quiet, but it’s a good place for little ones to run off some energy before a flight. It’s by the check-in counters, so it’s outside of security. It’s not actually a closed room, more of an alcove/lobby down a little hallway that has a half-height wall (the no-door thing can be a problem if you have an older child who’s prone to wandering).
Terminal C – The women’s room has an area similar to the one described above, though I didn’t notice a door.
