Baby's First Bedtime: Layering For Safe Sleep

how many layers should a newborn sleep in

Deciding what to dress your newborn in for sleep can be a stressful experience for new parents. It can be difficult to tell if your baby is too cold, too warm, or just uncomfortable. It's important to remember that overheating a baby is unsafe, and that cold babies don't sleep well. So, how many layers should a newborn sleep in?

Characteristics Values
Number of layers One more layer than an adult would need to stay warm in the same bedroom.
Alternatively, a single layer of clothing with a swaddle or sleep sack over it.
In warm weather, a nappy and singlet underneath a wrap.
In cool weather, a lightweight jumpsuit or layers of clothing under the wrap.
In some cases, a short-sleeve onesie without pants or a diaper is sufficient.
In winter, a long-sleeved/long-legged romper is ideal.
Considerations The room temperature should be comfortable for both the baby and the caregiver.
The baby's head should be uncovered to prevent overheating and hazards.
The baby should be placed on their back to sleep.
The crib or bassinet should be clear of loose items, blankets, pillows, and toys.
The wrap should not be too tight and should not cover the baby's head, ears, or chin.
The baby's temperature can be checked by feeling their back or tummy, which should be warm.

Swaddling

If you want to swaddle your newborn, it is recommended to use a product specifically designed for swaddling with a Velcro or zipper closure. Make sure to select the correct size based on your baby's weight and height. Choose a swaddle with fabric appropriate for the temperature of your home. It should be snug around the chest but still allow the baby to breathe easily. The bottom of the swaddle should be loose enough for the baby's legs to stay bent up and out, allowing their legs to strengthen and bend, which is important for hip development.

To swaddle your baby, spread the swaddle blanket on a flat surface in the shape of a diamond, with one corner pointing up. Fold the top corner down about 6 inches, and place your baby's head above the folded edge, with their body extending straight down. Take the left side of the blanket and wrap it over the left arm and chest, then tuck it underneath the right arm and back. Bring the bottom corner of the blanket up and tuck it under the first fold, below the baby's chin.

It is important to note that swaddling is not suitable for all babies. It can increase the risk of hip problems if the baby's legs are wrapped too tightly together and straight. Loose fabric can also become a strangulation or suffocation hazard. Additionally, swaddling is not recommended for babies who nap on the go, such as in a car seat, stroller, or carrier. If you notice your baby sweating, having flushed cheeks, or showing signs of overheating, consider removing a layer.

Room temperature

Keeping your newborn baby's room at the right temperature is essential to ensure they sleep safely and comfortably. The ideal room temperature for a baby is between 68°F and 72°F (20°C and 22°C). Some sources suggest that the ideal temperature is slightly lower, at 69°F (20.5°C) or 68°F to 70°F, while others suggest a slightly broader range of 62°F to 75°F.

It's important to be aware that keeping your home too hot can increase the risk of Sudden Infant Death Syndrome (SIDS). Therefore, it's critical not to overheat your baby. If your baby is too warm, they may be sweaty, with flushed cheeks, or their skin may feel damp. In this case, you should remove a layer of clothing or lower the temperature in the room. You can also use a ceiling or floor fan to control the temperature, ensuring that the plug is kept away from the baby.

On the other hand, if your baby is too cold, their core (chest, neck, back, and tummy) will feel cool to the touch. Their fingers and toes are not a good indicator of warmth, as these can be cooler than the rest of their body even if they are dressed appropriately. If your baby is too cold, you can add another layer of clothing or use a warmer sleep sack.

The number of layers your baby should wear depends on the room temperature. As a general rule of thumb, you should dress your baby in one additional layer than an adult would need to feel comfortable in the same room. For example, if you're wearing pajamas, your baby might wear a diaper and onesie, plus an additional layer like a swaddle or sleep sack. In the summer, lightweight, breathable fabrics such as cotton, linen, silk, hemp, or wool are ideal. In the winter, thicker fabrics and more layers are appropriate.

Safe clothing

When it comes to newborn sleep, safety is paramount. Here are some detailed guidelines on safe clothing practices to ensure your baby sleeps comfortably and securely:

Room temperature considerations

Firstly, consider the temperature of the room. The ideal room temperature for newborn sleep is between 68°F and 72°F (20°C - 22°C). However, it's important to note that this may vary depending on your geographical location and the time of year. Adjust your baby's clothing accordingly. If you feel too warm or too cold in the room, chances are your baby does too.

Layers

The general rule of thumb is to dress your baby in one more layer than an adult would wear in the same room. This could be a lightweight onesie, romper, or bodysuit as the first layer. You can then add a swaddle, sleep sack, or sleep suit as the second layer. These count as one layer and provide additional warmth. However, avoid layering swaddles, sleep sacks, or suits as this can increase the risk of overheating and suffocation.

Head and neck coverage

Keep your baby's head and neck uncovered during sleep. Avoid hats, beanies, or any headwear as babies cool themselves by releasing heat from their heads and faces. Headwear can also slip and cover your baby's face, posing a strangulation or suffocation hazard.

Safe materials and practices

Opt for breathable and lightweight fabrics like cotton. Ensure the swaddle or sleep sack doesn't go above your baby's shoulders, covering their head, ears, or chin. Check that it's not too tight around their chest and hips, allowing them to straighten their legs comfortably. Avoid any loose items in the crib, including blankets, pillows, toys, and loose clothing. These can pose safety hazards such as strangulation and suffocation.

Signs of overheating or discomfort

Monitor your baby for signs of overheating. If your baby's cheeks are flushed or they seem sweaty, they may be too warm. Reduce layers or opt for lighter ones, and ensure their tummy and back feel warm but not hot to the touch. Remember, a baby's hands and feet may feel cool, but this isn't a reliable indicator of their overall body temperature.

Baby's temperature

Keeping your baby at a comfortable temperature is essential for safe sleep. Overheating increases the risk of sudden infant death syndrome (SIDS) and causes discomfort, while cold babies don't sleep well.

The ideal room temperature for a sleeping baby is between 68°F and 72°F (20°C - 22°C). However, it's more important to consider the temperature of your home and your baby's bedroom, as babies can be comfortable and safe outside of the "recommended range" if they're dressed appropriately.

As a general rule, babies should wear one more layer than an adult would need to stay warm in the same room. This helps avoid over-bundling, which can lead to overheating. You can also consider how you would dress yourself for the temperature of your baby's bedroom and dress your baby in a similar number of layers.

Babies should always sleep without blankets and should be wrapped in a thin swaddle or sleep sack. A swaddle, sleep bag, and sleep suit count as one layer, and you can then add lightweight layers underneath depending on the temperature and season. For example, a short-sleeve and legless bodysuit or romper is ideal during warmer months, while a long-sleeved/long-legged romper will keep them warm during winter. In warm weather, a nappy and singlet underneath a wrap should suffice, while in cool weather, a lightweight jumpsuit or layers of clothing under the wrap can be added.

If your baby is too warm, they may have flushed cheeks or be sweaty, and you can switch to lighter clothing or even just a diaper. If your baby is too cold, their core (chest, neck, back, and tummy) will feel cool to the touch, and you can add an extra layer of clothing. However, it's important to keep in mind that a baby's fingers and toes are not a good indicator of their overall warmth.

Some sleeping bags and suits have a TOG (thermal overall grade) rating, which can help guide your decision on what to dress your baby in. However, this is just a guide, and you should always consider the temperature of the room and your baby's specific needs.

Co-sleeping

The American Academy of Pediatrics (AAP) and other health organizations recommend that babies sleep in their own crib or bassinet in the same room as their parents for at least the first six months. This arrangement is known as room-sharing and has been shown to significantly reduce the risk of Sudden Infant Death Syndrome (SIDS). Placing the crib or bassinet close to the parents' bed allows for easy monitoring and attendance to the baby's needs throughout the night.

One of the main concerns with co-sleeping is the risk of accidental suffocation or strangulation. A baby sleeping in the same bed as their parents may be accidentally rolled over onto, or they may become trapped in the bedding, pillows, or other items in the bed. Additionally, an adult bed is typically softer than a firm crib mattress, which can increase the risk of SIDS.

To minimize these risks, it is crucial to follow safe sleep practices. If you choose to co-sleep, ensure that your baby has their own designated space within the bed, free from any blankets, pillows, or other items that could pose a hazard. Always place your baby on their back to sleep, as sleeping on their belly or side increases the risk of SIDS.

It is also important to consider the temperature of the room and the number of layers your baby is wearing when co-sleeping. Overheating is a risk factor for SIDS, so it is essential to ensure your baby does not get too warm. Dress your baby in a single layer of clothing, such as a cotton onesie or sleeper, and use a thin swaddle or sleep sack to keep them comfortable. Avoid hats, as they can cause overheating and pose a suffocation risk if they fall off.

By following these guidelines and staying informed about safe sleep practices, you can make co-sleeping a safer and more enjoyable experience for both you and your newborn. Remember to always consult with your healthcare provider if you have any concerns or questions about your baby's sleep environment.

Frequently asked questions

The number of layers a newborn sleeps in depends on the temperature of the room. A good rule of thumb is to dress your baby in one more layer than an adult sleeper would wear in the same room. Newborns should be dressed in thin, breathable layers that can be easily adjusted to match the bedroom temperature.

Newborns should always be put to sleep on their backs with their faces and heads uncovered to prevent suffocation. The room temperature should be comfortable, and the crib or bassinet should be clear of loose blankets, pillows, toys, and other items. Swaddling is a safe option for newborns but should be stopped once the baby starts to roll over, typically around 3-4 months.

To check if your newborn is too hot or cold, feel the skin on their tummy or back. It should be warm but not hot. Newborns can quickly overheat if they fall asleep wearing hats, so it's important to keep their heads uncovered. Their hands and feet might feel cool, but this is not a good indication of their body temperature.
