Location: after Subway and the coffee place, before you turn to the exhibition halls (if coming from MRT)
I usually pop by this room before going to the exhibition halls and on my way back to the MRT/taxi. The main area houses the sink, changing stations, and water. If I remember correctly, there is also a highchair. Then there are 4 nursing cubicles, each with a chair, table and lamp. The chairs are really comfy, the type that you can just sink into. The door pulls across and locks. The ceiling is open though so it can get pretty noisy.
