Which mother statement about crib safety indicates a need for further instructions?

The statement indicating a need for further instructions is the assertion regarding the distance between the slats. This statement claims that the slat distance should be no more than 4 inches apart. In reality, current safety standards recommend that the space between crib slats should not exceed 2 3/8 inches (or about 6 centimeters) to prevent an infant from getting their head caught and potentially causing injury.

Ensuring that slats are within this guideline is critical for infant safety, as wider gaps could lead to suffocation or entrapment. The other statements reflect accurate and necessary safety practices. For example, ensuring drop-sides are securely locked, maintaining smooth wood surfaces, and removing large toys that pose a risk of suffocation all contribute to a safe sleeping environment for infants.
