Final answer:
Isolating infants mainly refers to safe sleep practices that reduce the risk of Sudden Infant Death Syndrome (SIDS), including placing infants on their backs to sleep and avoiding potential suffocation hazards in the crib.
Step-by-step explanation:
The practice of isolating infants to promote sleep is a topic closely associated with recommendations aimed at preventing Sudden Infant Death Syndrome (SIDS). Parents are advised to place infants on their backs to sleep in cribs free of suffocation hazards such as blankets, pillows, or padded crib bumpers. Moreover, to prevent overheating, infants should not have caps on their heads when put down to sleep. Abstaining from smoking in the home is another crucial recommendation health experts provide to protect children. These measures have contributed to a decline in SIDS incidents. Despite these precautions, early social contact is essential for infants' development as shown in research by Harlow, indicating the complexities involved in ensuring both the physical and psychological well-being of infants.
