What is one common hazard to remove from an infant's crib?

Loose bedding is identified as a common hazard to remove from an infant's crib due to the risk of suffocation and Sudden Infant Death Syndrome (SIDS). Infants have a natural instinct to move around while sleeping, and if they become trapped under loose blankets, sheets, or pillows, it can obstruct their ability to breathe, leading to dangerous situations. The recommendation from pediatricians is to use a fitted sheet on the mattress and avoid additional items like comforters and quilts.

The other choices present items that may be more acceptable in certain contexts or have specific guidelines regarding their use. For instance, a toy that the infant likes could be safe if it is securely placed out of reach or used during playtime rather than sleep. A baby monitor might be necessary for keeping an eye on the child from another room, and while a mobile can provide visual stimulation, it should be positioned out of reach of the baby or removed as the child grows to prevent any accidents.
