Abstract: Described herein are one or more implementations of a convertible diaper-changing tote bag. When unfurled into diaper-changing mode, the bag's fold-out diaper-changing pad is configured to fit onto a rigid horizontal changing platform (e.g., a changing station or changing table). As described herein, one or more implementations of the bag include at least one onmi-accessible storage receptacle that is accessible when the bag is both in diaper-changing mode (e.g., the pad is unfolded and in-place on the platform) and in tote mode (e.g., the pad is folded up).
