Amount of crying or fussiness has been associated with the concept of difficult temperament. In this study, we explored the associations between cry acoustics and temperament characteristics across the first 12 weeks of life in a group of healthy full-term infants. Maternal ratings of 12-week temperament, particularly negative emotional reactivity, were significantly related to both neonatal and 12-week cry acoustics. In addition, two acoustic variables, duration of cry utterance and fundamental frequency, were stable over the first 12 weeks of life.
