Harrison Y. The relationship between daytime exposure to light and night-time sleep in 6-12-week-old infants.
J Sleep Res. 2004 Dec;13(4):345-52.

Abstract: This project investigated the relationship between exposure to light and 24-hour patterns of sleep and crying in young, healthy, full-term babies living at home and following a normal domestic routine...Fifty-six babies (26 males and 30 females) were monitored across three consecutive days at 6, 9 and 12 weeks of age. There was an early evening peak in crying which was associated with reduced sleep at 6 weeks. Across the trials there was a gradual shift towards a greater proportion of sleep occurring at night. Sleeping well at 6 weeks was a good indication of more night-time sleep at 9 and 12 weeks. Babies who slept well at night were exposed to significantly more light in the early afternoon period. These data suggest that light in the normal domestic setting influences the development of the circadian system.

Our comment: This study confirms our recommendation to have infants awake during the day, and asleep at night, to the extent possible.
