Clothing For Newborns: What To Dress Them In For Sleep

what should newborns sleep in clothes

Deciding what newborns should sleep in can be a daunting task for new parents. The ideal room temperature for a newborn baby to sleep in is between 68°F and 72°F (20°C - 22°C). To maintain this temperature, newborns should be dressed in one additional layer of clothing than an adult would need to stay warm in the same bedroom. This is to prevent the risk of overheating, which can be dangerous for newborns. Newborns can be dressed in onesies, footed pyjamas, sleep sacks, or swaddles.

Dressing newborns for sleep: room temperature considerations

When it comes to dressing newborns for sleep, maintaining a comfortable room temperature is crucial to ensure your baby's well-being. Here are some essential considerations to keep in mind:

Ideal Room Temperature

The ideal room temperature for a newborn to sleep comfortably is generally agreed to be between 68°F and 72°F (20°C - 22°C). This temperature range helps prevent overheating while providing a cozy environment. However, it's important to remember that different homes have different temperatures, and babies can be comfortable outside this range as long as they are dressed appropriately.

Dressing for the Seasons

It is essential to reassess your newborn's sleep clothing as the seasons change. In colder months, you may opt for a t-shirt onesie under a full-body onesie or footed pajamas. During warmer periods, a short-sleeve onesie without pants or just a diaper under a swaddle may be more suitable.

Layering

Layering is a practical way to adjust to varying room temperatures. As a general rule, dress your newborn with one more layer than an adult would need to stay warm in the same bedroom. This could be a onesie with a swaddle or sleep sack, or a lightweight sleep sack with detachable sleeves during warmer months.

Signs of Overheating

Overheating in newborns is a serious concern and has been linked to an increased risk of Sudden Infant Death Syndrome (SIDS). To prevent this, it's crucial to monitor for signs of overheating. If your newborn's neck, hair, or core (chest, neck, back, and tummy) are sweaty, or their cheeks are flushed, they may be too warm. In such cases, reduce layers or opt for sleepwear with a lower TOG rating.

Safe Sleep Practices

To ensure your newborn's safety, follow safe sleep practices. Avoid loose items in the crib, such as blankets, pillows, toys, and pacifiers, as they pose a risk of suffocation and strangulation. Additionally, always put your newborn to sleep on their back, as sleeping on their belly or side increases the risk of SIDS.

In summary, when dressing your newborn for sleep, aim to maintain a comfortable room temperature between 68°F and 72°F, dress them in one more layer than you would wear, and monitor for signs of overheating. By following these guidelines, you can help ensure your newborn sleeps safely and comfortably.

Safe sleepwear options: swaddles, sleep sacks, and more

When it comes to putting your newborn down for a safe and comfortable sleep, there are several options to consider in terms of sleepwear. It's important to remember that the primary goal is to maintain a comfortable body temperature for your baby, preventing them from getting too cold or too warm. Here are some safe sleepwear options to consider:

Swaddles

Swaddling involves wrapping your baby snugly in a thin blanket or specialised swaddle cloth, providing a sense of security and comfort. It is a popular option for newborns and young infants. However, it is crucial to follow safe swaddling practices, such as ensuring your baby's hips can move freely to allow proper hip development and transitioning out of swaddling as they grow. Additionally, once your baby starts showing signs of rolling over, it's important to discontinue swaddling to prevent restricting their arm movement.

Sleep Sacks

Sleep sacks, also known as wearable blankets, are a safe and effective alternative to traditional blankets. They provide warmth without the risk of covering your baby's head, reducing the chances of overheating. Sleep sacks come in various weights and fabrics, allowing you to choose the most suitable option for the current temperature. They often feature detachable sleeves, making them versatile for different seasons. Sleep sacks are designed to be snug-fitting, reducing the risk of your baby's legs getting stuck in crib slats.

Onesies

Onesies, also called sleepers, are a type of lightweight sleepwear that can serve as an effective primary layer of sleepwear. They are typically made of breathable fabrics like cotton and can be worn under swaddles or sleep sacks for added warmth. Onesies with short sleeves and legs, or those left unfastened, can be a good option during warmer nights.

Footed Pajamas

Footed pajamas, also known as footie pajamas, are another option for newborn sleepwear. They provide coverage for your baby's feet, ensuring warmth during cooler nights. Look for options made with breathable fabrics like cotton to help regulate your baby's temperature.

Gown-Like Sleepwear

Some parents prefer sleepwear that is easy to open at the bottom, such as gowns. This design allows for quick diaper changes during the night without disturbing your baby too much.

Remember, the ideal room temperature for a baby's sleep is between 68°F and 72°F (20°C - 22°C). It is recommended to dress your baby in one additional layer than you would wear yourself to be comfortable. However, always be cautious of overheating, as it can increase the risk of Sudden Infant Death Syndrome (SIDS).

How to prevent overheating

Newborns should sleep in clothing that keeps them at a comfortable temperature, so a blanket is unnecessary. Sleep clothing can be layered to suit the bedroom temperature and provide any needed warmth. As a general rule, newborns should be dressed with only one more layer than an adult would need to stay warm in the same bedroom. This rule can help avoid over-bundling, which can lead to safety risks from overheating.

  • Maintain a comfortable room temperature: Keep the baby's room temperature between 68°F to 72°F (20°C to 22°C). Use a room thermometer to monitor and maintain a comfortable temperature.
  • Ensure proper ventilation: Provide adequate air circulation in the baby's room to prevent heat from building up. Use fans or open windows if needed to improve ventilation.
  • Avoid external heat sources: Keep the baby's sleeping area away from direct sunlight, radiators, heating pads, portable heaters, and fireplaces. Remove any excessive insulation that may contribute to overheating.
  • Dress the baby appropriately: Opt for light and breathable clothing, such as cotton or lightweight wool sleep sacks. Choose sleepwear that regulates temperature well, like four-season sleep sacks. Avoid excessive layers, thick clothing, or heavy blankets, as they can lead to overheating.
  • Monitor for signs of overheating: Pay close attention to your baby's temperature and look for signs such as flushed skin, excessive sweating, rapid breathing, irritability, or lethargy. Touch their ears, neck, or chest to feel if they are too warm. If your baby is dressed too warmly, reduce the layers or opt for sleepwear with a lower TOG rating.
  • Stay cautious during illness: If your baby is unwell or has a fever, their body temperature may already be elevated, making them more susceptible to overheating.
  • Avoid hats and loose items: Do not put a hat on your baby while sleeping, as it reduces their ability to release heat through their head. Remove any loose items, such as pacifiers, hair bows, or mittens, as they are not considered safe for sleep.

How to prevent underheating

Keeping your newborn baby warm and cosy at night is important, but overheating can be dangerous. Newborns are still learning to regulate their body temperature, so it's important to keep them at a comfortable temperature.

The ideal room temperature for a baby is between 16°C and 20°C. You can use a room thermometer to check this. If the room is too warm, try turning down the thermostat, or if it's a hot day, follow the 'summer rules' of opening a window and using a fan (not pointing directly at the baby).

The best way to gauge your baby's comfort level is to consider how you feel in the room. If you are comfortable, your baby probably is too. If you are too warm, your baby will be too warm, and if you are cold, your baby will be cold. If you feel hot or sweaty, your baby will likely be too hot. Signs that your baby is too warm include flushed cheeks, sweating, or heavy breathing. You can check your baby's temperature by gently touching the back of their head or their belly. Their fingers and toes are not a good indicator of warmth, as they will usually be cooler.

If your baby is too cold, you can add layers. The recommended clothing for a baby sleeping in a room at 16-20°C is a vest and a sleepsuit, with a lightweight sleeping bag. If the temperature drops below 20°C, you can add a layer, such as a sleepsuit and a vest, or a swaddle.

Dressing newborns for sleep while travelling

When it comes to dressing newborns for sleep while travelling, there are a few key considerations to keep in mind. Firstly, it is important to maintain a comfortable body temperature for the baby. This means preventing both overheating and over-bundling, which can lead to safety risks, and ensuring the baby is not too cold. The ideal room temperature for a sleeping baby should be between 68°F and 72°F (20°C-22°C). However, it is important to remember that different homes have different temperatures, and babies can be comfortable outside of this range as long as they are dressed appropriately.

When travelling, take into account the climate and temperature of the sleeping area. Dress your baby in layers so you can easily adjust their clothing as needed. A good rule of thumb is to dress a baby in one additional layer than an adult would need to stay warm in the same bedroom. For example, a onesie can be an effective primary layer of sleepwear, with a sleep sack or swaddle as a second layer. Sleep sacks are preferred over loose blankets, which can increase the risk of suffocation and sudden infant death syndrome (SIDS). When using a swaddle, ensure it is done safely, allowing the baby's hips to develop properly and transitioning out of it as they grow.

It is also important to avoid loose articles of clothing that could cover the baby's face and inhibit breathing. This includes hats, bows, and scarves. Instead, opt for snug-fitting PJs made from breathable fabrics like cotton. When selecting sleepwear, consider gown-like clothing that is easy to open at the bottom, making diaper changes more convenient. Additionally, be mindful of safety hazards such as small objects or buttons on clothing that could become choking hazards.

To maintain a sense of familiarity and comfort while travelling, you can use a sleep sack or wearable blanket with a familiar scent. Communicate your baby's typical sleep routine and preferences to caregivers if they will be staying in daycare or with a babysitter. Providing familiar sleepwear and a security object can help your baby feel more secure in a new environment.
