The Safe Way: Newborns And Fleece For Sleep

can newborns sleep in fleece

When it comes to newborn sleep, safety and comfort are top priorities. One common question among new parents is whether it's safe to dress their baby in fleece. The short answer is yes, but only if the fleece is made from 100% natural fibres like cotton, which allows the body to breathe. This is crucial, as overheating has been linked to an increased risk of SIDS. While fleece is a popular fabric for baby sleepwear and cangsleep sacks, it's important to consider the TOG (Thermal Overall Grade) rating to ensure your baby doesn't get too warm. Dressing your newborn in layers can help regulate their temperature, and it's generally recommended to stick to simple outfits like onesies and swaddles or sleep sacks.

Is it safe for newborns to sleep in fleece?

It is generally advised to avoid dressing newborns in fleece pajamas, especially if they are also swaddled, as this can cause the baby to overheat, increasing the risk of SIDS. Instead, it is recommended to use a swaddle or sleep sack for newborns, and if necessary, to add layers of clothing underneath, such as a onesie or light pajamas.

However, in very cold environments, fleece can be used to keep newborns warm. In such cases, it is important to ensure that the fleece is made from natural fibers such as cotton, which allow the body to breathe, reducing the risk of overheating. Organic cotton fleece is the healthiest option for babies and toddlers. It is also important to consider the TOG (Thermal Overall Grade) rating of the fleece, which indicates how warm it will keep the baby. A higher TOG rating means the garment is more insulating. Fleece typically has a high TOG value of around 3.0, so it is important to balance this with other layers to prevent overheating.

It is crucial to monitor a newborn's temperature to ensure they are comfortable and safe. The core of the body, including the chest, neck, back, and tummy, is the best indicator of whether a baby is too hot or cold. If the baby's core feels warm but not sweaty, and their cheeks are not flushed, then the temperature is likely comfortable. If the baby is too hot, removing layers or switching to lighter fabrics can help. Conversely, if the baby feels cold, adding layers or using a warmer swaddling cloth or sleep sack can be considered.

Additionally, it is important to avoid covering a newborn's head with a hat while sleeping, as this can also increase the risk of SIDS by causing overheating and potential suffocation. Instead, the general recommendation is to dress newborns in the same way adults would dress themselves for sleep in the same environment, adding no more than one extra layer.

What are the best fabrics for newborn sleepwear?

The best fabrics for newborn sleepwear are those that help regulate the baby's temperature, ensuring they are comfortable and safe. Here are some recommended fabrics for newborn sleepwear:

Cotton

Cotton is a popular choice for newborn sleepwear as it is gentle on the baby's delicate skin. It is a natural fibre that allows the body to breathe, reducing the risk of overheating. Organic cotton, in particular, is a healthy option for newborn sleepwear. It is important to note, however, that finding 100% cotton, especially organically grown cotton, can be challenging. Most cotton products contain a blend of cotton and synthetic fibres, such as polyester.

Fleece

Fleece is a common fabric used for newborn sleep sacks and pyjamas, especially in colder climates. It is important to note that fleece is typically made from various fibres, including natural and synthetic ones. When considering fleece sleepwear for newborns, opt for those made with 100% natural fibres, such as cotton, to ensure breathability and comfort. The TOG value, or Thermal Overall Grade, of fleece is around 3.0, indicating its high insulating capacity. Therefore, fleece sleepwear is best suited for chilly weather or cool nurseries to prevent overheating.

Bamboo

Bamboo is another recommended fabric for newborn sleepwear. It is a breathable and luxurious option that helps maintain the baby's temperature.

Muslin

Muslin is suggested as a lightweight and breathable fabric option for newborn sleepwear, especially during warmer months.

In addition to fabric choice, it is essential to consider the number of layers a newborn wears while sleeping. The general recommendation is to keep it simple with light pyjamas, a onesie, or a light sleep sack/swaddle. For colder rooms, you can layer these options, such as light pyjamas under a sleep sack. However, it is crucial to avoid overdressing a newborn, as it can increase the risk of overheating and Sudden Infant Death Syndrome (SIDS).

How to regulate a newborn's temperature

It is important to regulate a newborn's temperature to ensure their immediate and long-term health. A newborn's temperature should ideally be maintained at between 96.8°F and 99.5°F (36°C and 37.5°C). If their skin temperature drops even by a single degree, a baby's oxygen use can increase by 10%, so it is crucial to ensure they are kept warm.

To regulate a newborn's temperature, it is recommended to use a swaddle or sleep sack. A newborn's body surface area is around three times greater than that of an adult's relative to their body weight, so they can lose heat up to four times faster than an adult. This makes them particularly susceptible to temperature changes, and they may struggle to regulate their own temperature, especially if they are premature or low birth-weight.

In cold environments, a newborn's temperature can be regulated by dressing them in light pajamas or a onesie, and then placing them in a sleep sack or swaddle. If the baby is still cold, a warmer swaddling cloth or sleep sack with a higher TOG rating of 1.5-2.5 can be used. In extremely cold environments, fleece pajamas may be appropriate, but these should be avoided if the baby is also being swaddled, as this can cause the baby to overheat.

In warm environments, a newborn should be dressed in light and loose clothing, such as a short-sleeved cotton bodysuit or t-shirt with a sleep sack over them. If the temperature is particularly high, the sleep sack should be removed. It is important to avoid overheating, as this can increase the risk of SIDS. To check if a baby is too hot, you can place your hand on their neck, tummy, or chest. If their skin feels hot or sweaty, remove one or more layers of clothing.

What are the signs of a newborn being too hot or cold?

It is crucial to ensure that a newborn is dressed appropriately to maintain a comfortable temperature, as they are more susceptible to overheating or getting too cold. Here are some signs that a newborn is too hot or too cold:

Signs of a newborn being too hot:

  • Flushed skin and sweating: If a baby is sleeping somewhere warm and their skin feels hot or sweaty, remove a layer of clothing or blankets.
  • Heat rash: Look out for tiny red bumps in skin folds, around the neck, and on the bottom.
  • Heat exhaustion or heat stroke: Symptoms include heavy sweating, a rapid or weak pulse, and very hot or cold, clammy skin. This is a medical emergency.
  • Dehydration: Excessive sweating can lead to dehydration, indicated by a lack of tears, fewer wet diapers, and lethargy.
  • Lethargy: Overheating can cause babies to become lethargic and less responsive.

Signs of a newborn being too cold:

  • Crying: Babies are more likely to cry if they are cold at night.
  • Fussiness: A baby that is too cold may wake up more frequently and be fussier.

To check if a newborn is too hot or cold, you can place your hand on their neck, tummy, or chest to feel if they are too warm. You can also use a thermometer to monitor their body temperature, which should be between 97.7°F and 100.4°F. Additionally, it is important to dress newborns in layers, so you can easily adjust their clothing as needed. In general, it is recommended to dress a newborn in one more layer than an adult would wear in the same environment.

Regarding fleece sleepwear for newborns, it is important to choose those made with 100% natural fibers, such as cotton, which allow the body to breathe. Polyester fleece is widely available but may cause discomfort as it traps moisture, leading to a wet, clammy feeling.

How to layer newborn sleepwear

When layering newborn sleepwear, it is important to consider the temperature of the room and the baby's comfort. Here are some tips to help you layer your newborn's sleepwear appropriately:

Choose the Right Fabric:

Select soft, breathable fabrics such as cotton or merino wool that will keep your baby comfortable and regulate their temperature. Avoid synthetic fabrics like polyester that can trap heat and cause discomfort.

Keep it Simple:

Opt for light pajamas, a onesie, or a short-sleeved bodysuit as a base layer. You can add a sleep sack or swaddle over this if needed. Remember, you can always add or remove layers depending on the temperature.

Consider the Room Temperature:

Adjust the number of layers based on the room temperature. In colder rooms, you may want to add a long-sleeve bodysuit or zip-up onesie under the sleepwear. In warmer rooms, a single layer of light sleepwear may be sufficient.

Use a Sleeping Bag or Suit:

Consider using a safe infant sleeping bag or suit, especially if your baby doesn't like being wrapped. These can help keep your baby warm, and you can choose one with a suitable TOG (thermal overall grade) rating for the temperature.

Avoid Overheating:

It is important to prevent your baby from overheating. Keep their head uncovered, and avoid hats or beanies while they sleep. Check your baby's temperature by feeling the back of their neck, chest, or tummy. If they feel hot, remove a layer.

Swaddle Safely:

If you choose to swaddle your newborn, ensure the wrap is not too tight around their chest and hips, and they can straighten their legs. Swaddling can provide a comforting sensation, but it should be done safely, especially in warm weather.

Remember, the general rule is to dress your newborn in "one more layer than you." It's better to add or remove layers as needed to ensure your baby stays comfortable and safe during sleep.
