The short answer
Use a cool-mist humidifier, out of reach, a few feet from the crib, set to keep the room around 40 to 50 percent, and clean it daily and weekly.
Type
Cool-mist humidifiers (evaporative or ultrasonic) avoid the burn risk of hot water and steam. Ultrasonic units are quietest; use distilled water to avoid white dust.
Placement
- At least a few feet from the crib, on a stable surface, with the cord secured and out of reach.
- Mist directed away from bedding and walls.
- A hygrometer in the room to keep below 50 percent.
Cleaning
Empty and rinse daily and descale weekly; stagnant water can grow bacteria.
SafetyNever add essential oils or medications to a humidifier unless its maker says it's designed for them, and follow safe-sleep guidance for the crib itself.
