How to Keep an Infant Warm at Night

There are many reasons why you should know to keep an infant warm at night. Infants have underdeveloped immune systems and are more prone to catching colds and illnesses, especially during the colder months. Ensuring that your baby is warm and comfortable while they sleep can prevent them from getting sick and help them get a good night’s rest.

How to Keep an Infant Warm at Night

The main  advantage of keeping an infant warm at night is to ensure their comfort and safety. Infants have a harder time regulating their body temperature compared to adults, so it is important to provide them with adequate warmth during the night. You can find step-by-step instructions on how to keep an infant warm at night in this blog article.

Step-by-step Instructions for How to Keep an Infant Warm at Night

Step 1: Inspect the Room Temperature

Make sure that the temperature in the room is comfortable for an infant. The ideal temperature for a baby to sleep comfortably is between 68-72°F (20-22°C). Use a thermostat or thermometer to check the temperature and adjust accordingly.

Step 2: Layer Up

Dress your baby in layers so that you can easily add or remove clothing as needed. This will help you regulate your baby’s body temperature throughout the night. Infants should not sleep with loose blankets as they can be a suffocation hazard. Instead, use a sleep sack or swaddle blanket to keep your baby warm and cozy.

Step 3: Choose the Right Fabric

When dressing your baby for bed, opt for clothing made from breathable and natural fabrics such as cotton or bamboo. These fabrics will help regulate your baby’s temperature and prevent overheating. Ensure that your baby’s crib is not placed near a drafty window or door. This will help avoid cold drafts from reaching your baby as they sleep.

Step 4: Use a Heating Pad or Hot Water Bottle

Place A Heating Pad

Place a heating pad or hot water bottle in the crib before putting your baby down to sleep. This will provide added warmth and comfort for your little one. Dry air can cause discomfort and irritate your baby’s nasal passages. Consider investing in a humidifier to add moisture to the air and keep your baby’s room at a comfortable humidity level.

Step 5: Avoid Overheating

While it is important to keep your infant warm, it is also crucial to avoid overheating. Check on your baby throughout the night and ensure that they are not sweating or feeling too hot. Babies are not able to regulate their body temperature as well as adults, so it’s important to monitor them for any signs of temperature changes. If your baby feels cold or clammy, add an extra layer or adjust the room temperature.

Step 6: Trust Your Instincts

As a parent, you know your baby best. Trust your instincts and use your judgement when it comes to keeping your infant warm at night. If you feel that they are too cold or too hot, make the necessary adjustments to ensure their comfort and safety.

By following these simple steps, you can ensure that your baby stays warm and cozy throughout the night. Remember to always prioritize safety and comfort when it comes to keeping your infant warm at night. Additionally, consult with your pediatrician for any specific concerns or recommendations based on your baby’s unique needs.

Safety Precautions  for How to Keep an Infant Warm at Night

  1. Make sure the room temperature is set to a comfortable and safe level. The ideal temperature for an infant’s room at night is between 68-72 degrees Fahrenheit.
  2. Dress your baby in appropriate clothing for the weather and room temperature. Avoid dressing them too warmly as it can lead to overheating.
  3. Use a sleep sack or wearable blanket instead of loose blankets to keep your baby warm and safe while sleeping. Loose blankets can increase the risk of suffocation or SIDS.
  4. Keep your baby away from direct heat sources, such as heaters, electric blankets, or fires. These can pose a serious danger to infants and should be avoided at all costs.
  5. Place your baby’s crib or bassinet away from windows and drafts to prevent cold air from reaching them. Use curtains or blinds to block out any drafts.
  6. Consider using a humidifier in your baby’s room if the air is too dry. This can help prevent skin irritation and keep their nasal passages moist, making it easier for them to breathe.
  7. Always check on your baby throughout the night to make sure they are not too hot or cold. Adjust their clothing or bedding as needed to maintain a comfortable temperature.
Use a Sleep Sack

By  following these safety precautions, you can ensure that your baby stays warm and comfortable throughout the night while also keeping them safe from any potential hazards. Remember to always prioritize your baby’s safety and well-being above all else.

Are There Any Warning Signs That Your Infant is Too Hot or Too Cold While Sleeping?

There are a few warning signs that your infant may be too hot or too cold while sleeping. These include:

  • Sweating: If your baby is sweating, it could be a sign that they are too hot. However, sweating can also occur if they are wearing too many layers, so make sure to check their clothing and remove any extra layers if necessary.
  • Clammy Skin: Similar to sweating, if your baby’s skin feels clammy or damp, it could be a sign that they are too hot. This can also occur if they are wearing too many layers.
  • Red Face: A red face can indicate that your baby is overheating. If their face feels hot to the touch, they may need to cool down.
  • Rapid Breathing: If your baby is breathing quickly, it could be a sign that they are too hot. This is because their body is trying to cool down by expelling warm air.
  • Restlessness: If your baby is tossing and turning, it could be a sign that they are uncomfortable due to being too hot or too cold.
  • Excessive Crying: Babies may cry if they are too hot or too cold, so pay attention to their cries and try adjusting the temperature or layers of clothing accordingly.
  • Changes in Color: If your baby’s skin appears to be mottled or bluish, it could be a sign that they are too cold. This is because their body is trying to conserve heat by reducing blood flow to their extremities.
  • Cool to the Touch: If your baby’s hands or feet feel cool to the touch, it could be a sign that they are too cold. This is especially important to note if their core body temperature feels warm.

It’s important to monitor these warning signs and make adjustments as needed to ensure your infant is sleeping at a comfortable temperature.

How Can You Prevent Sudden Changes in Temperature in Your Infant’s Room During the Night?

There are a few steps you can take to prevent sudden changes in temperature in your infant’s room during the night. First, make sure the room is appropriately insulated. This means sealing any drafts or gaps around windows and doors, as well as ensuring the walls and ceiling are properly insulated. This will help maintain a consistent temperature in the room, making it less likely for sudden changes to occur.

Second, invest in a digital thermometer for your baby’s room. This will allow you to easily monitor the temperature and make adjustments as needed.

It’s important to keep the room between 68-72 degrees Fahrenheit (20-22 degrees Celsius) for optimal sleep conditions for infants. You can also dress your baby in appropriate sleepwear for the current temperature. If it’s a colder night, opt for heavier sleepwear or use a sleep sack to keep them warm. On warmer nights, stick to lightweight clothing or just a diaper.

Another helpful tip is to limit the use of electronics in your baby’s room, as they can generate heat and cause temperature fluctuations. This includes keeping the TV off and avoiding using a baby monitor with video capabilities.

Avoiding Using a Baby Monitor


In conclusion,  ensuring that an infant stays warm at night is crucial for their overall health and well-being. As we have discussed, there are several ways to keep an infant warm at night, including dressing them in appropriate clothing, using a sleeping bag or swaddle, and maintaining a comfortable room temperature.

However, it is important to remember that every baby is different and may have varying needs when it comes to staying warm at night. Therefore, it is essential to pay attention to your baby’s cues and adjust accordingly. Additionally, always make sure to check on your baby throughout the night and monitor their temperature to ensure they are not too hot or too cold.

I have a smart beautiful,curious 6 year old daughter, a handsome 11-year-old son, an intelligent and tech geek 15 years old son and a creative, artistic 12-year-old stepson. With each of my kids being five years apart, I feel that I’m now continually phasing in and out of each stage of parenting! I’ve learned a lot about the way children learn and behave, especially in a school setting with regards to curriculum. I enjoy sharing that insight through my writing and hope that it can help others.
