During insight meditation, what does the meditator note in-between the rising and falling of the abdomen?

I practice insight meditation (Theravada tradition), noting the rising and falling of the abdomen. It was suggested that one should make a mental note once per second, neither too frequently, nor too slowly. However, there are moments between the instances of rising and falling, when the abdomen does nothing. What should the practitioner note in these moments?"Not moving"? "Resting"? I note "touching", as I become aware of the sensation of my T-shirt touching the skin on the abdomen. Is this right practice?
