Bedsharing between infants and parents interacts with many factors to increase the risk of SIDS, eg maternal smoking, alcohol or drug consumption, overtiredness, excessive bedding and younger infant. However, bedsharing also encourages breastfeeding, settles babies, reduces parental tiredness and increases mother-baby interactions. We studied infants in the natural setting of their own home, in their usual situation (bedsharing or cot-sleeping) to identify risks and benefits, and to understand how bedsharing could be made safer for all infants. Methods: Overnight home video and physiological recordings of 40 bedshare infants (5-27 weeks), were compared with 40 cot infants matched for age and study season. Video data provided a log of infant/parent sleep positions, movements and interactions. The physiological recordings measured respiratory pattern, respiratory airflow, inspired CO2, oxygen saturation (SaO2), heart rate and core, peripheral and environmental temperatures. Results: All infants maintained normal core temperatures overnight although bedshare infants had a higher shin temperature [35.43 vs 34.60°C at 2hrs after sleep onset (difference 0.83, 95% CI: 0.18 to 1.49)]. Bedshare infants had thicker bedding (RR:2.35 (95% CI:1.76 to 3.14) and more face covered time [0.9h/night vs 0.2 (RR:5.62, 95% CI: 3.08 to 10.25)]. Awakenings in the bedshare group were more common, of shorter duration, and caused less change in infant temperatures. Exposure to >3% CO2 occurred in 18 bedshare infants and 1 swaddled, cot-sleep infant. The maximum exposure time was the same for both groups (60mins). These levels of CO2 significantly (p |
