Abstract: A fluid intake measuring system for an infant comprises a change mat containing or carrying a weighing pad responsive to the weight of an infant placed on the change mat, and a display responsive to the weighing pad to indicate weight gain or fluid volume intake of an infant placed on the mat prior to and following feeding. In an embodiment the system is integrated into a carrying bag. The mat when folded into a storage condition lies against an outer side of the bag, and in its unfolded operative state extends outwardly from a lower part of the side of the bag.
