Answer:
The correct option is D: "(1) fairly common; (2) fairly common"
Step-by-step explanation:
SIDS is a common occurrence for babies that are less than a year old. It is when an apparently healthy looking infant dies in its sleep. It might have to do with brain defects or an infection in the respiratory system, among other reasons. Co-sleeping is defined as sleeping with the baby in the same room or perhaps even on the same bed. It can get dangerous if the baby gets somehow trapped and its airways blocked, putting the baby's life at serious risk.
