In this manuscript we describe a case of electroencephalography artifact during polysomnography that occurred in the context of mother co-sleeping with her child. The potential interference from a co-sleeping parent's electrocardiography, as illustrated in this case, may be an under-recognized source of electroencephalography artifact in pediatric patients.
