There are two new nursing rooms across from gate C5 in IAH (George Bush International Airport) terminal C. Both are nice, new, and lock. One is directly off the walkway with a sink, bench, and baby chair. The other is inside the ladies room. It also has a sink, bench, and baby chair, but it also has an outlet. So if you have an electric pump, you need to use the room inside the ladies room since the other has no outlets. Also note that C5 is a hike, so if you're short on time or have a manual pump you may want to hop in a family restroom instead since they are all over the terminal (but also had no outlets that I could find).
