Sleep temperatures

Maintaining an appropriate sleep temperature for babies is important to ensure their comfort, safety, and promote healthy sleep. Here are some guidelines regarding baby sleep temperatures:

  1. Recommended Room Temperature: The ideal room temperature for babies to sleep comfortably is between 68°F (20°C) and 72°F (22°C). This temperature range helps prevent overheating or becoming too cold during sleep.

  2. Dressing for Sleep: Dress your baby in appropriate sleepwear based on the ambient temperature. Use lightweight clothing in warmer conditions and layer their clothing or use sleep sacks in cooler temperatures. It's essential to strike a balance between keeping them warm enough without overheating.

  3. Overheating Risks: Overheating is a concern as it can increase the risk of Sudden Infant Death Syndrome (SIDS). Avoid excessive bundling or using heavy blankets or duvets that can cause overheating. Instead, opt for lightweight, breathable fabrics and ensure the sleep environment is well-ventilated.

  4. Check for Comfort: Rather than relying solely on room temperature, it's important to monitor your baby's comfort directly. Feel their chest or back to ensure they aren't too hot or too cold. If your baby feels sweaty or their skin feels hot to the touch, remove a layer or adjust the room temperature accordingly.

  5. Bedding and Sleep Environment: Use a firm mattress and a fitted sheet that fits snugly to reduce the risk of suffocation or entanglement. Avoid placing pillows, stuffed animals, or excessive bedding in the crib, as they can pose safety hazards and increase the risk of overheating.

  6. Consider Seasonal Changes: Be mindful of seasonal temperature variations and adjust the sleep environment accordingly. During hot summer months, use fans or air conditioning to maintain a comfortable sleep temperature. In colder winter months, you may need to adjust room heating or add additional layers to keep your baby warm.

It's important to note that individual preferences and sensitivities to temperature may vary among babies. Paying attention to your baby's cues, such as their behavior, sweating, or discomfort, can provide valuable insights into their optimal sleep temperature. Regularly monitor the room temperature and adjust sleepwear and bedding accordingly to create a safe and comfortable sleep environment for your little one.


When dressing your baby, it's important to consider their comfort, the prevailing weather conditions, and their age. Here are some general clothing guidelines for babies based on age and temperature ranges:

Newborn (0-3 months):

Temperature Range: 68°F to 74°F (20°C to 23°C)

  • Short or long-sleeved onesies or bodysuits

  • Soft cotton pants or leggings

  • Socks or booties

  • Light cotton or muslin swaddle blankets for sleep

  • A lightweight hat to keep their head warm

  • Avoid overdressing or using heavy blankets to prevent overheating

Infant (3-6 months):

Temperature Range: 65°F to 72°F (18°C to 22°C)

  • Similar to newborns, use onesies or bodysuits with pants or leggings

  • Layer with a lightweight cardigan or sweater if needed

  • Soft socks or booties

  • Cotton sleep sacks or wearable blankets for sleep

  • Hat or cap for outdoor activities

Baby (6-12 months):

  • T-shirts or bodysuits with pants, leggings, or skirts

  • Light sweaters or jackets for cooler temperatures

  • Socks or booties

  • Cotton sleep sacks or wearable blankets for sleep

  • Sun hat for outdoor activities

Toddler (1-3 years):

  • T-shirts or tops with pants, leggings, or shorts

  • Light sweaters or jackets for cooler temperatures

  • Socks or shoes

  • Sleepwear such as pajamas or sleep sacks appropriate for the room temperature

  • Sun hat for outdoor activities

Remember, these are general guidelines, and you should always consider your baby's individual needs and preferences. It's important to check your baby's comfort by feeling their skin or back to ensure they are not too hot or too cold. Adjust their clothing and layers accordingly based on the specific weather conditions and your baby's response to the environment.
