This application discusses systems and method for entraining oromotor pattern development, such as the suck, in the orofacial system of an infant having neurological impairments or developmental disabilities. The system includes a baglet, an entrainment device, and a processor. In varying examples, the system additionally includes one or a combination of: a baglet pressure sensor, a memory, a timing circuit, a valve, a receiver assembly, a display device, and one or more data acquisition, data analysis, and stimulus-control software. Options and variations for each feature of the system are various. The present systems provide patterned, rhythmic stimulation to the infant's orofacial system to stimulate and entrain brain development, such as oromotor pattern development.
