Keeping a baby comfortable at night is a challenge for many parents. Babies can't tell you if they're too hot or cold, so it's up to you to find the right room temperature for them. A baby's room should be kept cool but comfortable, with good air circulation. The ideal temperature for a sleeping baby is between 65 and 72 degrees Fahrenheit (20 to 22.2 degrees Celsius). This range helps to reduce the risk of overheating, which has been linked to sudden infant death syndrome (SIDS). To gauge your baby's comfort level, consider how you feel in the room. If you feel too cold, your baby probably does too, and if you feel hot, your baby will likely also feel hot.

A comfortable room temperature for a baby is between 65°F and 72°F (18.3°C to 22.2°C)
Keeping a baby's room at a comfortable temperature is important for their sleep and overall health. The ideal room temperature for a baby to sleep in is between 65°F and 72°F (18.3°C to 22.2°C). This range may vary slightly depending on the season and the number of blankets used. For example, in the summer, a thermostat set to 72°F may feel cold, whereas in the winter, the same temperature may feel too hot.
It is important to note that babies are sensitive to changes in room temperature as their bodies are still growing and developing. Therefore, it is recommended to keep their room cool but comfortable, with good air circulation. An ideal room temperature for a baby will also reduce the risk of overheating, which has been linked to Sudden Infant Death Syndrome (SIDS).
To ensure your baby is comfortable, observe them for signs of being too hot or too cold. If your baby is sweating, flushed, or breathing heavily, they may be too warm, and you can reduce the number of layers they are wearing or lower the room temperature. If their skin feels cool to the touch, they may be too cold, in which case you can add layers or slightly increase the room temperature.
Additionally, it is important to avoid overdressing your baby for sleep. Dress them in one extra layer compared to what an adult would wear. For example, a one-piece sleeper with a sleep sack should be sufficient. In colder weather, you can add another layer, such as a long-sleeved onesie under the sleeper. However, avoid using heavy blankets, as they can cause your baby to overheat and restrict their breathing.
By maintaining a comfortable room temperature and dressing your baby appropriately, you can help ensure they get a safe and restful sleep.

Avoid overdressing your baby or using heavy blankets
The ideal room temperature for a 5-month-old baby to sleep in is between 68 to 72 degrees Fahrenheit (20 to 22 degrees Celsius). This temperature range creates a comfortable environment for your baby to sleep in without being too hot or too cold.
Babies are more sensitive to changes in room temperature because their bodies are small and still growing. Overdressing your baby or using heavy blankets can lead to overheating, which increases the risk of sudden infant death syndrome (SIDS). SIDS is the leading cause of death for infants between birth and 12 months, and it is important to take steps to reduce the risk.
To avoid overdressing your baby, consider the room temperature and dress them in one layer beyond what an adult would wear in the same air temperature. For example, if you are wearing flannel pyjamas under a heavy comforter, your baby may only need to wear a single layer of clothing. You can also place your hand on your baby's chest or ears to test their skin temperature. If their cheeks are flushed or their core (chest, neck, back, and tummy) feels clammy or sweaty, they are probably too warm. In this case, you can reduce the layers under their sleepwear or opt for a sleep sack/swaddle with a lower TOG rating.
Instead of using heavy blankets, opt for minimal bedding in the crib. You can use light, breathable blankets that only come up to your baby's chest, or a lightweight sleep sack. Swaddling your baby can also provide added warmth and a sense of security, but make sure to stop once they can roll over to avoid the risk of suffocation. It is important to ensure that your baby's sleep sack is the right size and does not have any additional fabric that can create a choking hazard.

Signs your baby is too hot include flushed skin, sweating, and irritability
The ideal room temperature for a sleeping baby is between 65 and 72 degrees Fahrenheit (or 18.3 to 22.2 degrees Celsius). This range is recommended because it reduces the risk of overheating, which has been linked to sudden infant death syndrome (SIDS).
Signs that your baby is too hot include flushed skin, sweating, and irritability. You can test the temperature of their skin by placing your hand on their chest or neck. If your baby is too warm, their skin may feel hot to the touch, and they may be fussy or irritable. Their cheeks, neck, or hair may also be sweaty, and they may be breathing heavily.
To prevent your baby from overheating, avoid overdressing them and keep their crib free of blankets, loose sheets, pillows, and stuffed toys, as these can also lead to suffocation or choking. Instead, opt for minimal bedding and consider using a lightweight sleep sack to keep them comfortable. It is also recommended to put your baby to sleep on their back, as this is the safest sleep position and helps reduce the risk of SIDS.
Additionally, you can use a fan in their room to circulate the air and keep them cool, but don't point it directly at the baby. During the summer or in warmer climates, choose clothing made of lighter fabrics for your baby, such as a onesie with socks or lightweight sleepwear.

A fan in the room can help keep your baby cool and reduce the risk of SIDS
Keeping your baby's room at the right temperature is crucial to their safety and comfort. A fan in the room can help keep your baby cool and reduce the risk of SIDS.
Firstly, it's important to understand the ideal room temperature for a baby. The recommended temperature range for a baby's room is between 68 to 72 degrees Fahrenheit or 20 to 22 degrees Celsius. This range creates a comfortable environment for your baby to sleep soundly and safely. You can dress your baby appropriately for the temperature, just as you would dress yourself. However, it's important to remember that babies are more sensitive to temperature changes due to their smaller size and still-developing bodies.
Maintaining good air circulation in the room is essential. A fan helps to achieve this by keeping the air moving and preventing the room from becoming too stuffy or warm. Good air circulation not only makes the room more comfortable but also helps reduce the risk of SIDS. A study published in the Archives of Pediatrics & Adolescent Medicine found that the risk of SIDS was 72% lower in rooms with a fan compared to those without. Additionally, opening a window reduced the risk by 36%.
It's important to ensure that the fan is not blowing directly on the baby. You can use any type of fan, such as a ceiling fan, standing fan, or tower fan, as long as the airflow is not directed at the baby. The fan should be placed in a position that improves air circulation without causing a draft. This way, the fan helps regulate the temperature and keeps the room comfortably cool without posing any risk to the baby's health.
Finally, it's crucial to be mindful of the potential for your baby to overheat. Overheating is linked to an increased risk of SIDS. Dress your baby in minimal layers to prevent them from getting too warm. Avoid bundling them up too tightly, especially in the winter. Instead, opt for light, breathable clothing and bedding. Additionally, pay attention to signs that your baby may be too hot, such as sweating, flushed cheeks, or a rash. If you notice these signs, you can remove some layers and lower the room temperature to help cool them down.

You can also open a window to keep the room cool, but don't point the fan or open window directly at the baby
Keeping a 5-month-old baby's room at an ideal temperature is important for their safety and comfort. While there are no fixed rules, a general rule of thumb is to keep the room at a temperature that a lightly clothed adult would find comfortable. This is usually between 68 to 72 degrees Fahrenheit or 20 to 22 degrees Celsius.
To keep the room cool, you can open a window to create a natural breeze. Open windows on the other side of the house and keep doors open to create a breeze flowing through the house. However, make sure not to point the open window directly at the baby, as direct airflow can be unsafe for them.
Using a fan in the room is another option to keep the room cool and improve air circulation. However, like the open window, do not point the fan directly at the baby. Positioning the fan away from the baby is crucial for their safety. You can also try keeping the blinds or curtains closed during the day to prevent the sun from warming up the room.
Additionally, it is important to consider the baby's clothing and bedding. When the weather is warm, the baby does not need to wear as much clothing. Dress them in lightweight, breathable clothing, and avoid overdressing them. Also, opt for minimal bedding in their crib, and consider using a lightweight sleep sack instead of blankets.
