Are nursing rooms free at Changi?

Question

The airport's website shows there are baby care rooms at Changi. But I cannot find anywhere if there is a fee to use the room. Are the baby care rooms free to use?

Their website also says there are strollers that can be loaned on a first-come first-serve basis (assuming they are fee free). Does anyone know if the airport has enough strollers? Are they easily available?

This is for a traveller on an international flight, transiting through Changi.

Answer 1

This article complains about a man barging into a baby care room at Changi airport to fill up his hot water flask, which strongly implies there is no charge to use the rooms.
