10 Easy Steps on How to Keep Baby Warm in SNOO

Step 1. Dress Baby Appropriately:

Dress Baby Appropriately

Make sure that you dress your baby in several layers of clothing so that they can stay both comfortable and warm. Investing in onesies with built-in foot covers is a great way to keep their little toes snug! It’s also important to have a hat that protects their ears and head from the cold.

Step 2: Add a Blanket or Cover:

Whether it’s an SNOO blanket or some other kind of cover, make sure to use one for added insulation. This will help hold your baby’s body heat and protect them from any drafts in the room. If you’re using an SNOO, make sure to tuck the sides of the blanket or cover it securely.

Step 2. Set the Thermostat:

Set your thermostat to a comfortable temperature, usually around 68 degrees Fahrenheit (20°C). You may need to increase or decrease the temperature depending on how cold it is outside. This also helps you monitor the room’s temperature if it gets too hot or cold.

Step 3. Place Heating Pad:

Use a heating pad placed beneath the mattress of the baby’s crib to help keep them warm during sleep time. Make sure you set it to low heat so it doesn’t become too hot for your little one! Additionally, make sure the wire is not within reach of the baby.

Step 4. Use SNOO Blanket or Cover:

If you are using SNOO, a great way to keep your baby warm is by layering blankets or covers on top of it. The added layers will help keep the temperature warm and comfortable for your little one during sleep time.

Step 5. Humidifier/Dehumidifier:

In colder climates, keeping the humidity level in check is important. You can use a humidifier or dehumidifier to regulate the amount of moisture in the air, which can directly affect how comfortable baby feels during sleep time. Try to keep the humidity level between 40%-60%.

Humidity Level in Check is Important

Step 6: Place Room Thermometer:

Place a room thermometer near the baby’s crib so that you can easily monitor the temperature throughout the night. This way, if it gets too cold for your little one, you’ll know immediately and be able to make adjustments to keep them comfortable.

Don’t forget to check the temperature before you put your little one down for the night.

Step 7: Check for Drafts:

Make sure to check for any drafts in the room that can make it too cold for your baby. Cover windows with curtains and seal up any cracks around doorways or frames to protect them from the cold air. It will also help if you keep the door to their room closed.

Step 8: Keep Doors Closed:

It’s also important to close doors while your baby sleeps so that cold air from outside stays out and their body heat gets trapped inside. This will help increase the room’s temperature, making it more comfortable for your little one during sleep time. Moreover, it will also help reduce the chance of any drafts in the room.

Step 9: Don’t Overheat Your Baby:

Remember not to overheat your baby, as this can make them uncomfortable and cause irritation. Try to keep their room temperature between 68-72°F (20-22°C). Be careful not to cover them too much, making them overheat.

Step 10: Monitor Baby’s Temperature:

Lastly, monitoring the baby’s temperature throughout the night is important. If they feel warm to the touch or if you notice that they are tossing and turning in bed, it may be time to adjust the temperature of their room. Remember, a cool, comfortable room is key for getting your little one to sleep soundly!

Following all these steps will help ensure that your little one stays safe and warm during cold winter nights! Remember, making sure your baby is snug as a bug while sleeping should always be a high priority!

5 Additional Tips and Tricks

1. Layer Up: Make sure you dress your baby in layers. Start with a onesie or undershirt and add other clothing items like pants, a sleep sack, and a light blanket on top. This will help keep your baby warm without being too hot or uncomfortable.

2. Temperature Control: The Snoo adjusts the temperature of the bassinet to provide optimal comfort for your little one. To ensure your baby is warm enough, you can adjust the temperature level through the app according to their comfort.

3. Blanket Hack: Putting extra blankets over and around your Snoo can help retain heat while avoiding excess pressure on your baby’s body that could be created from heavier bedding materials like duvets or comforters.

4. Keep the Room Warm: The temperature in your baby’s room should be between 18.5 and 21°C for optimal comfort. Use a thermostat to keep track of the temperature and ensure it’s warm enough so your baby stays comfortable and cozy.

5. Check Regularly: Make sure you check on your baby regularly, especially if they are bundled up with extra layers or blankets. The Snoo will adjust itself according to the room temperature, but you must still take precautions and ensure your baby is not too warm.

Remember that if your child gets too hot while sleeping, it can increase their risk of SIDS (Sudden Infant Death Syndrome).

Following these guidelines ensures your little one stays safe and comfortable while sleeping in the SNOO. Remember always to keep an eye on your baby and adjust accordingly!

5 Things You Should Avoid

1. Overheating: While you want to keep your baby warm, it’s important not to go overboard. Too much heat can be dangerous for infants and increase their risk of SIDS.

2. Using Heavy Blankets: Avoid using any heavy blankets or duvets when you dress your baby in the SNOO, as these items could create excess pressure on their body and cause discomfort.

Avoid Using Any Heavy Blankets

3. Room Temperatures Below 18°C: Your baby’s room should never be too cold; this can make them uncomfortable and risk hypothermia. Make sure the temperature stays between 18 and 21°C for optimal comfort.

4. Overdressing: Don’t overdo it when dressing your infant – one onesie and some light clothing items (like pants) should be enough. Adding too many layers can affect Snoo’s temperature control functions.

5. Avoiding Temperature Checks: Avoiding regular temperature checks can put your baby at risk for overheating. Use the Snoo app to monitor the temperature level and make sure it’s within a comfortable range for your little one.

By avoiding these tips, you can ensure that your baby stays safe, warm, and comfortable while sleeping in the SNOO. Don’t forget to adjust the settings as needed and check your baby regularly! This way, you can rest easy knowing that your precious one is cozy and secure.


How to keep baby warm in SNOO ensure your baby is safe and comfortable while sleeping in their SNOO can help you avoid a lot of heartache and stress.

The best solution for keeping baby warm is probably buying the appropriate SNOO Sack size for your little one’s age, season, and environment. Look for products that you trust, like 100% natural fibers like flannel or cotton muslin, as they are optimal for regulating temperature.

Moreover, adding layers will keep your body heat trapped inside the SNOO sack, and insulation will be added simultaneously. Investing in a product that will act like an extra layer of warmth between your little one’s body and their sleeper so they stay cozy throughout the night may be a good idea too.

Lastly, be sure to organize everything well ahead of time instead of waiting until bedtime to get it all together. By prepping beforehand, you’ll know exactly how much warmth you need to add when putting them in their SNOO and can avoid guesswork when it comes to getting ready for sleep time!
