Keep Volume Very Low
Infant hearing is more sensitive than adult hearing. Sound experts generally recommend keeping any sleep sound well below the volume adults might find comfortable — quiet enough that it’s barely audible from across the room.
Choose Simple, Repetitive Tracks
Babies and toddlers respond well to predictability. Simple, looping ambient tracks without dramatic shifts tend to work better than complex, evolving compositions.
Avoid All-Night Continuous Volume Right Next to the Crib
Placing the speaker across the room rather than directly beside the crib reduces unnecessary volume exposure while still providing a calming background.
When to Check With a Pediatrician
If you have any concerns about hearing sensitivity or a specific medical condition, it’s best to check with your child’s pediatrician before making sound machines or music a regular part of their sleep routine.
