Final answer:
The best position for infants and toddlers to maintain an open airway is to place them on their backs when put down to sleep. This reduces the risk of SIDS and allows for proper airflow.
Step-by-step explanation:
The best position for infants and toddlers to maintain an open airway is to place them on their backs when put down to sleep. This is also known as the back-to-sleep position. Placing the infant on their back helps to reduce the risk of sudden infant death syndrome (SIDS) and allows for proper airflow.
According to research recommendations, infants' cribs should not contain any items that pose suffocation threats, such as blankets, pillows, or padded crib bumpers. It is also advised to avoid placing caps on their heads to prevent overheating. Additionally, people in the child's household should refrain from smoking in the home.
