What should be done to prevent suffocation when using a toy box for toddlers?

To prevent suffocation when using a toy box for toddlers, choosing a box without a lid or one that locks in the open position is crucial. A design without a lid eliminates the risk of the lid closing accidentally and trapping a child inside, which is a significant hazard associated with toy boxes. This option ensures that if a child climbs into the box while playing, they are not at risk of suffocation due to being unable to exit.

The other options, while they may provide some level of functionality, do not address this specific safety concern effectively. A toy box with a tightly closing lid could pose a serious danger if a child were to get inside, as they could become trapped. Keeping only large toys in the box does not mitigate the risk of suffocation, as a child could still climb in. Similarly, filling the box with soft, plush toys may create a comfortable environment but does not prevent the fundamental suffocation risk associated with a lid.
