Kalang Wave Mall has an area designated for nursing mums, but it's not the best and it's very small compare to other malls in Singapore.
Location: Level 1 & 2 Size: Average (accommodates only 1 stroller) Available: Sink, small hard plastic chair (not very comfortable) Not available: Electrical point, hot & cold water dispenser, waiting area, bottle warmer, high chair.
The Nursing mothers area separated from diaper changing area. It's minimally decorated and has few amenities but relatively clean. However, the lack of electrical points in the cubicle may make expressing milk more inconvenient. In addition, not all the nursing rooms (there is one beside each toilet) have a chair (albeit an uncomfortable plastic one) in it so you may find that it is not suitable for nursing.
