Why Dressing Your Baby Right for Sleep Matters

Safety Guidelines (2026): What Has Changed?

Most recent guidance from the American Academy of Pediatrics (AAP) and WHO reaffirms longstanding safe sleep rules: place baby on their back in a bare, firm crib or bassinet, avoid loose bedding (blankets, pillows, toys), and keep the sleep space free of clutter. Updated 2022–2026 guidelines stress: never overbundle, avoid hats, and keep room-sharing (not bed-sharing) for 6–12 months reduces SIDS risk by up to 50%. For layering, use only as many layers as needed for room temperature.[AAP Safe Sleep]

Understanding Overheating and SIDS Risks

Overheating is a known factor for Sudden Infant Death Syndrome (SIDS). The risk increases with excess bedding, synthetic fabrics, and hats. Studies highlight that a room temperature of 68–72°F (20–22°C) and TOG-rated sleep sacks are ideal for risk reduction. Babies should wear only one more layer than an adult would find comfortable.

The Science of Sleepwear Fabrics

Clinical studies and parent testing show:

Bamboo viscose: The most effective at moisture-wicking, hypoallergenic, and reduces eczema flare-ups.
Organic cotton: Gentle and durable, especially GOTS-certified, but less effective at wicking moisture than bamboo.
Wool: Superior thermal regulation but premium priced.
Synthetics (polyester, fleece): Trap heat and are not recommended.

Seasonal Guide – How to Dress Your Baby for Sleep, Step-by-Step

Dressing for Summer & Hot Climates

Choose minimal layers (diaper or short-sleeve cotton/bamboo bodysuit) with a lightweight (0.5 TOG) sleep sack. Avoid hats or socks. Use fans for gentle airflow when rooms exceed 75°F (24°C). Check baby’s chest—not hands or feet—for warmth. Explore summer sleep sacks

Layering for Fall & Spring

As temperatures fluctuate, use layered bodysuits beneath a 1.0–1.5 TOG sleep sack. Add or remove a single layer as the room temp changes, ensuring baby is warm to touch but not sweaty.

Keeping Baby Warm Without Over-Bundling in Winter

Rooms below 68°F (20°C): Opt for long-sleeve footed pajamas, a bodysuit, and a 2.5–3.5 TOG sleep sack. Choose wool or thick organic cotton for insulation. Never use loose blankets or heavy hats indoors.

Room Temperature Tips & No-Cost Hacks for Better Baby Sleep

How to Judge Nursery Temperature Without a Thermometer

Check your own comfort: if you feel chilly or sweaty, adjust for baby. Feel your baby’s upper back/neck, not limbs—skin should be warm, not hot or damp. Room-sharing lowers SIDS risk and helps you monitor temperature changes.

Simple Adjustments to Keep Baby Comfortable Year-Round

Open/close nursery windows for natural airflow.
Use a ceiling or oscillating fan (not blowing directly on baby).
Close blinds during the day in summer or draft-proof windows in winter.
Dress baby in fewer layers for higher room temp, more for colder rooms.

What to Do if Baby’s Room Runs Too Hot or Cold

In hot rooms, remove a layer or switch to more breathable fabrics (bamboo). In cold, add a footed sleeper or use a higher TOG bag. Never use space heaters/fireplaces. Layer smart, not heavy.
