Abstract Thirteen all‐night sleep recordings were obtained from 3 infant pigtailed ( Macaca nemestrina ) monkeys raised on a cloth surrogate mother under conditions of social isolation. Totally implantable biotelemetry systems were used to record the sleep physiology from the unrestrained animals. Sleep stages and night‐to‐night variability were virtually identical to values previously found in 8 mother‐reared group‐living infants. Sustained alterations in the early rearing environment, even though considerably modifying the organism's development, did not appear to result in differences in sleep organization.
