1. The study examined 20 infants aged 2-3 months who slept in their parents' bed and in a cot next to the bed on consecutive nights while being monitored physiologically and via video.
2. The majority of infants (14/20) had their airways (mouth and nose) covered at some point during the bed night, compared to only 2/20 infants on the cot night. However, airway covering did not consistently affect oxygen saturation levels or heart rate.
3. All instances of airway covering were initiated by parents, with parents terminating most (70%) instances and infants terminating the rest (30%). Some potential compression by parental limbs was observed but lasted less than 15 seconds and was
