Sleeping Arrangements in Families with Twins

This paper describes home sleeping arrangements used by parents of twins and investigates whether room sharing (twins in the same room as parents) or cobedding (crib-sharing between twins) influences parental night time sleep duration or sleep quality. A secondary analysis of data obtained from a longitudinal study of sleep in 104 families with twins was undertaken. Over 65% of twins were cobedded at 4 weeks; this decreased to approximately 42% by 13 weeks of age. Approximately 64% of families practiced room sharing at 4 weeks, this decreased to approximately 40% by 13 weeks of age. Mothers and fathers who both room shared and cobedded their twins at 9 weeks of age were most likely to experience restricted sleep duration when compared to other sleeping arrangements. Results suggest that parents of twins may not be following the most recent AAP recommendations regarding safe infant sleep for multiple birth infants.
