Dressing a Baby for Sleep: Core Principles and Current AAP Safety Guidelines (2026)
Understanding Overheating and SIDS Prevention
Babies are at risk of overheating, which increases SIDS risk. Always dress babies in light layers to avoid overheating. Feel the back of the neck or chest for warmth, not hands or feet.
What’s New in Safe Sleep Guidance in 2026?
- No hats or coverings on the head during sleep for any age up to 12 months
- Loose blankets remain unsafe; approved sleep sacks are recommended
- Focus on breathable fabrics, even in colder climates
Materials and Fabrics: What’s Best for Baby Sleepwear?
- Cotton: Breathable, gentle on skin, good for most climates
- Bamboo: Soft, moisture-wicking, hypoallergenic
- Fleece: Warm for cold rooms, avoid if room is above 21°C (69°F)
- Avoid wool directly on skin, as it may cause irritation
Mastering Layers: How to Choose Sleepwear and Sleep Sacks by TOG Rating
What is TOG? Decoding Sleep Sack Ratings for Parents
TOG stands for “Thermal Overall Grade.” It measures the warmth of a sleep sack. The higher the TOG, the warmer the garment.
Updated TOG Chart: Matching Sleepwear to Room Temperature
| Room Temp (°C/°F) | Recommended TOG | Example Sleepwear |
|---|---|---|
| 24-27°C / 75-80°F | 0.2-0.5 TOG | Short-sleeve bodysuit + light muslin sack |
| 21-23°C / 69-73°F | 1.0 TOG | Cotton sleeper + regular sleep sack |
| 16-20°C / 61-68°F | 2.5 TOG | Long-sleeve bodysuit + warm sleep sack |
| Below 16°C / 61°F | 3.5 TOG | Footed pajamas + thick fleece sleep sack |

Region and Climate-Specific Advice: Customizing Baby’s Bedtime Outfit
Dressing for Humid Climates vs. Dry, Cold vs. Hot Regions
- Humid: Prefer bamboo or cotton to wick moisture; avoid thick layers
- Dry, Cold: Layer cotton under fleece, use 2.5+ TOG sleep sacks
- Dry, Hot: Stick to single, light breathable layer
AC-Heavy Homes and Temperature Fluctuations: What Parents Need to Know
Use consistent TOG-rated sleepwear. Check the baby’s warmth if the AC is strong or room temperature drops overnight. Dress your baby as you would dress yourself for comfort, plus one light layer.
International Tips: What Changes Across Countries?
- Always check local safety guidelines
- Japan: Lightweight swaddles popular in summer
- Nordic countries: Wool is popular, but use under layers to avoid skin irritation
- Australia: Pay close attention to summer heat with minimized clothing
Safety First: What to Avoid When Dressing Baby for Sleep
Common Mistakes: Hats, Loose Blankets, and Unsafe Accessories
- No hats or beanies—babies regulate heat through their heads
- No loose blankets, pillows, or stuffed toys in the crib
- Avoid strings, ribbons, or ties on sleepwear
Signs of Overheating or Chilling: How to Respond
- Signs of overheating: Damp hair, flushed cheeks, sweating, rapid breathing—remove one layer at once
- Signs of chilling: Cool chest/back, fussiness, mottled skin—add a light layer
Nighttime Diapering and Safe Swaddling Guidelines
- Use quick-access pajamas for efficient nighttime changes
- Swaddle safely with arms in or out based on age (stop swaddling when rolling begins)
- Ensure hips are loose and unrestricted in swaddle or sleep sack
