Preterm infants prefer to be awake at night.
Wakefulness distribution during a 24-h period was studied in ten low-risk preterm and near term infants through video-recording. The highest amount of wakefulness was found in the night-time period between 02:00 and 05:00 h. This result is different from what was observed in infants during the first year of life, and similar to what was found in the foetus.
