Answer:
3.
Step-by-step explanation:
According to several investigations, 60% of infants (at around 1 month of age) sleep in the same room as their parents in middle- and upper-class North American families. For example, the AAP (American Academy of Pediatrics) recommends that infants share the parents' room but not their bed. Given that infants could die of sleep-related causes, for at least six months, they recommend that they share a room for at least the first six months.
