Which child has the greatest risk for choking and suffocating?

The child with the greatest risk for choking and suffocating is a toddler playing with a construction set. Toddlers are known for their exploratory behavior and tendency to put objects in their mouths. Construction sets often include small parts that can easily be a choking hazard. At this developmental stage, toddlers may not have fully developed the motor skills needed to handle objects safely, increasing their risk of accidentally swallowing items or getting them caught in their throat.

The other scenarios presented involve children in situations that generally pose a lower risk for choking. A 5-year-old eating yogurt is typically capable of eating without much danger, as yogurt is a soft food. An infant asleep without a blanket is generally safe, as there are no choking hazards present; the absence of a blanket also reduces the risk of suffocation. A 3-year-old drinking juice is usually able to manage drinking liquid without a significant risk of choking. Therefore, among all the options, the toddler engaged with small construction set pieces faces the highest likelihood of choking or suffocating due to the nature of the objects involved.
