Disclosed are barrier assemblies for infant changing platforms, methods for making and methods for using such infant barrier assemblies, and infant changing systems with a changing platform for cradling an infant and a barrier assembly for restraining and pacifying the infant. In an example, a barrier assembly is removably or permanently attached to an infant changing platform. The barrier assembly includes a base with first and second stanchions coupled to the base proximate first and second lateral sides of the changing platform, respectively. First and second ends of a flexible screen are attached to the first and second stanchions, respectively, such that the screen extends transversely across the changing platform and gently rests on a portion of an infant's trunk. One or both of the stanchions may be removable from and/or movable with respect to the base to facilitate positioning a child on and removing the child from the platform.
