What temperature should a baby's room be?

Pediatric institutions including Cleveland Clinic and Children's Health point to a comfortable range of 68 to 72 degrees Fahrenheit for infant sleep. The American Academy of Pediatrics itself does not prescribe a specific number — its 2022 policy recommends dressing baby in no more than one layer more than an adult would wear comfortably in the same environment.

What humidity level is recommended for a baby's room?

The U.S. Environmental Protection Agency recommends keeping indoor humidity between 30 and 50 percent. Below that range can dry airways; above 50 percent encourages mold and dust mites. The American Academy of Pediatrics specifically recommends cool-mist humidifiers over warm-mist for infant rooms because warm-mist units carry burn risk.

Where should a crib be placed relative to vents and windows?

Avoid placing the crib directly under or beside an HVAC vent. Direct airflow creates uneven temperature exposure and skews any temperature reading from a thermostat, baby monitor sensor, or thermometer. The AAP flags overheating as a SIDS risk factor. Keep cribs away from windows as well — the AAP recommends arm's-length distance from furniture and windows, and CPSC documents window blind cords as a strangulation hazard.

How far should a baby monitor be from the crib?

The U.S. Consumer Product Safety Commission recommends keeping baby monitors and their power cords at least 3 feet away from every edge of the crib — top, bottom, and all four sides. CPSC has documented at least seven infant strangulation deaths from monitor cords placed too close to cribs. Never mount a monitor on a crib rail. Reassess placement as baby grows, especially once they start pulling up.

What is the safest way to set up a crib?

Follow the ABCs of safe sleep: baby sleeps Alone, on their Back, in a Crib. Use a firm, flat mattress with a fitted sheet only — no blankets, pillows, stuffed animals, bumpers, positioners, or wedges for babies under 12 months. Room-share without bed-sharing for at least the first 6 months, ideally the first year, which the AAP associates with up to 50 percent reduction in SIDS risk. After 12 months, the safety guidance softens.

What kind of lighting is best in a baby's room at night?

Pediatric sleep specialists generally recommend dark rooms for infant sleep. If a nightlight is used, red or amber is preferred — blue and white light suppress melatonin and can disrupt sleep cycles, even at low intensity. Glowing LEDs from monitors, sound machines, and chargers add up at baby's eye level.

How should a sound machine or white noise be used safely?

The AAP's 2023 noise exposure policy recommends locating sound machines as far from baby as possible and keeping the volume as low as possible. Pediatric research referenced in the policy points to at least 7 feet of distance and roughly 50 decibels — about the volume of a quiet shower. The AAP also gives a simple test: if you'd raise your voice to talk to someone an arm's length away, it's too loud.

Should a nursery have smoke and carbon monoxide detectors?

Yes. The U.S. Consumer Product Safety Commission and National Fire Protection Association recommend a working smoke detector within hearing distance of every sleep area, tested monthly with batteries replaced at least once a year. If the home has any gas appliances — stove, water heater, dryer, fireplace — the CDC also recommends a carbon monoxide detector on every floor and near sleep areas. Combo smoke and CO units are around $30 and replace existing smoke detectors directly.
