Final answer:
Parents can reduce the risk of SIDS by placing the baby on their back to sleep and ensuring a smoke-free environment.
Step-by-step explanation:
Two important things that parents can do to reduce the risk of an infant dying from sudden infant death syndrome (SIDS) are to place the baby on their back to sleep and provide a smoke-free environment. Research suggests that these practices, along with avoiding items that pose suffocation threats such as blankets, pillows, or padded crib bumpers, and not placing caps on an infant's head during sleep to prevent overheating, can significantly lower the chances of SIDS. Additionally, people in the child's household should abstain from smoking to further ensure the baby's sleep environment is safe.
