As parents, we often find ourselves awake at night, worrying about our little ones. Are they too hot? Too cold? How to dress baby for bed to ensure they get the best sleep possible? As a new parent myself, I found myself asking these questions time and time again.
Key Takeaways
Dress your baby in one extra layer than what you’d wear, using breathable fabrics like cotton; regularly reassess their sleepwear with changing seasons for optimal comfort.
Understand TOG ratings to select the right sleep sack warmth for your baby, and modify sleepwear layers by checking your baby’s core temperature rather than hands or feet.
Ensure a safe sleep environment by avoiding loose bedding and using sleep sacks to reduce SIDS risks; always keep the crib free of toys, pillows, and loose blankets.
Crafting the Ideal Sleep Wardrobe for Your Baby

When it comes to dressing our little ones for bed, there’s more to it than just choosing the cutest pajamas. We must consider the temperature, both in the room and outside, and adjust their clothing accordingly to prevent overheating or chilling, which can lead to sleep-related infant deaths. Trust me, it’s a balancing act that every parent must master.
One general rule is to dress your baby in one additional layer than what you would wear at night in the same environment. Your baby’s core temperature is a better indicator of their overall body temperature than their hands or feet, so make sure to check it regularly. Moreover, as the seasons change, it’s recommended to reassess your baby’s sleepwear to guarantee their comfort and readiness for a sound sleep.

Dressing for Dreamy Summer Nights
During the summer months, it’s tempting to dress our babies in adorable sundresses or tiny tank tops for bed. However, the key is to choose lightweight, breathable sleepwear that allows air to flow freely, keeping our little ones cool and comfortable. A simple short-sleeved cotton or organic cotton bodysuit or T-shirt, layered with a muslin or cotton swaddle or sleep sack, is perfect for hot summer nights.
On particularly warm nights, a bodysuit or T-shirt on its own is perfectly fine. Ultimately, the aim is to promote comfortable and uninterrupted sleep for your baby while also maintaining a well-ventilated, safe sleep environment.
Ensuring Cozy Winter Slumbers
Winter introduces unique challenges when dressing our babies for bed. It’s essential to strike a balance between keeping them warm but not excessively so. Overdressing can cause your baby to sweat, increasing the risk of dehydration and discomfort, disrupting their sleep.
In cold weather, layering becomes essential. Here are some tips to keep your baby warm and safe:
Use footed pajamas or fleece sleepwear to provide the necessary warmth.
If it’s particularly cold, consider using a sleep sack for an extra layer of coziness.
Remember to keep the crib free of loose bedding and other objects to ensure a safe sleep environment.
Transitional Attire for In-Between Seasons
As we navigate the transitional seasons of spring and fall, dressing our babies for bed can often feel like a guessing game. The fluctuating temperatures require flexible baby wear options, such as sleep clothing, that can easily be adapted to the changing conditions.
For these transitional seasons, long-sleeved onesies, offering warmth and coverage, serve as an excellent choice. If necessary, additional layers, such as a wearable blanket or a light sweater, can be added. Sleep sacks with removable sleeves are also a great option, allowing you to adjust your baby’s warmth as necessary.
Remember, the best materials for dressing babies in different weather are merino wool, cotton, bamboo, and organic blends as they are soft, comfortable, and help regulate the baby’s temperature.
How to Dress Baby for Bed: Balancing Warmth and Safety

Now, let’s explore the intricacies of layering. Layering extends beyond just providing warmth; it’s a balancing act between warmth and safety. As a general guideline, our babies should wear one extra layer compared to what we would wear to be comfortable in the same environment. But remember, it’s not just about the number of layers; it’s also about the type of clothing and its thermal properties.
Understanding TOG ratings can be a game-changer when it comes to choosing the right sleep sack or swaddle for your baby. TOG ratings signify the amount of warmth a garment provides, helping parents make an informed decision about the right layers for their baby.
Decoding TOG Ratings for Sleep Sacks
Though decoding TOG ratings might initially seem like deciphering a secret language, rest assured that it’s more straightforward than it appears. Essentially, the higher the TOG rating, the warmer the sleep sack, and vice versa. For example, a TOG rating of 0.5 to 1.0 is ideal for summer, providing a light insulation layer suitable for temperatures of 75°F (24°C) or higher.
Understanding TOG ratings can help you adjust your baby’s sleepwear according to the room temperature, ensuring their comfort. If your baby feels too warm, you can opt for a sleep sack with a lower TOG rating.
When to Adjust Layers
Knowing when to modify the layers is key to ensuring your baby’s comfort. Baby’s comfort can be determined by feeling the back of their neck or tummy. If they feel hot or sweaty, it might be time to remove a layer or choose a sleep sack with a lower TOG rating.
The type of fabric used for the layers also plays a significant role in maintaining comfort. Natural fabrics like:
cotton
linen
silk
hemp
cashmere
wool
are excellent choices as they allow the skin to breathe and regulate body temperature effectively.
The Lullaby Trust suggests that if the room is between 16-20°C, you should dress your baby in one more layer than what you’d wear to be comfortable.
Navigating Safe Sleep Practices

For all parents, safeguarding our babies’ sleep is a paramount concern. It involves creating a safe sleep environment and understanding the importance of using items like sleep sacks to ensure baby sleep and what to avoid in the crib.
Sleep sacks offer several benefits for your baby’s sleep:
They replace the need for loose bedding, which can pose a suffocation risk.
They help regulate your baby’s temperature while providing a cozy and secure sleeping space.
Ensuring the crib is free of pillows, toys, and loose bedding is paramount in creating a safe sleep environment.
The Role of Sleep Sacks in Safe Infant Sleep
Sleep sacks are pivotal in promoting safe infant sleep. They are essentially wearable blankets that replace the need for loose blankets in the crib, which can pose a risk of suffocation and sudden infant death syndrome (SIDS).
In addition to being safe, sleep sacks also promote motor development as they allow babies to move around, kick, and wiggle, helping their muscles develop. While babies can start using sleep sacks as early as two months, some may not take to them until around six months of age.
Clearing the Crib: What to Avoid
In terms of what belongs in a baby’s crib, adopting a minimalist approach is beneficial. Keeping the crib clear of:
loose blankets
comforters
mattress toppers
pillows
stuffed animals
This is a crucial step in ensuring a safe sleep environment.
Loose objects pose a risk of suffocation and SIDS, and it’s recommended to keep nothing else in the crib with your baby under one year. So, while that cute stuffed animal might seem like a good idea, it’s best to save it for when your child is older.
Special Considerations for Newborns and Young Infants

When selecting sleepwear, newborns and young infants necessitate particular care. In the first weeks of life, swaddling can be a valuable method to help newborns feel secure and aid in sleep. However, it’s important to swaddle safely and know when to transition to other sleepwear options.
Regularly checking your baby’s temperature is also essential. It can help inform you if adjustments need to be made to their sleepwear or the room temperature.
The First Weeks: Swaddling and Beyond
Swaddling can provide a sense of security and comfort for newborns, mimicking the snug feeling they experience in the womb. However, safe swaddling is essential. Swaddles should be light and thin and wrapped snugly around the baby’s body, allowing for movement of the hips and knees.
The swaddling phase doesn’t last forever, though. Once your baby starts showing signs of rolling over, it’s time to transition to other sleepwear options for safety reasons. If you’re unsure about swaddling techniques or when to transition, don’t hesitate to ask your pediatrician for advice.
Monitoring Baby's Temperature
Keeping an eye on your baby’s temperature can help ensure they’re comfortable during sleep. The back of their neck or tummy is a good place to check for an accurate reading. If your baby seems unwell or uncomfortable, checking their temperature every two to four hours can provide valuable information.
Remember, if your baby is too warm or cold, adjustments may need to be made to their sleepwear or the room temperature. As always, if you’re unsure, consult your pediatrician for guidance on how to dress your baby correctly for sleep.
Creating a Comfortable Sleep Environment

The creation of a comfortable sleeping environment extends beyond merely the sleepwear of your baby. The room temperature and humidity levels also play a crucial role in ensuring your baby sleeps comfortably. Generally, if you feel comfortable in the room, it’s likely your baby will too.
Preserving the optimal room temperature and humidity level significantly contributes to forming a sleep-conducive environment for your baby. It can help prevent dryness or excessive moisture, impacting your baby’s comfort and sleep quality.
Ideal Room Temperature Range
Determining the perfect room temperature for your baby’s sleep might appear challenging. However, the recommended range is between 68 and 72 degrees Fahrenheit (20-22 degrees Celsius). A room temperature higher or lower than this range can disrupt your baby’s sleep.
Remember, babies can’t regulate their body temperature as well as adults can. So, it’s essential to keep a check on the room temperature and adjust their sleepwear accordingly to ensure they remain comfortable throughout the night, which is essential for a baby to sleep.
Humidity Levels and Baby's Comfort
Similar to temperature, the comfort of your baby is significantly influenced by the room’s humidity level. The recommended humidity level is between 40 and 60 percent. Too low humidity can cause dryness and irritation, while high humidity can lead to mold and mildew growth, which can be harmful to your baby’s health.
There are various ways to maintain the ideal humidity level in your baby’s room. Using a whole-home humidification system or a smaller plug-in humidifier can help keep indoor humidity levels between 40 and 60 percent.
The No-Hat Rule for Bedtime
Although it may appear illogical, it’s advisable to refrain from having babies wear hats during sleep. This is because:
A hat can slip off and cover a baby’s head, making it hard for them to breathe.
Babies release heat through their heads, so wearing a hat can make them too hot.
Wearing a hat during sleep can potentially increase the risk of sudden infant death syndrome (SIDS).
Smart Shopping for Baby's Sleepwear
As you shop for your baby’s sleepwear, prioritize safety, comfort, and functionality over solely considering style. Natural and organic materials, such as organic cotton, are softer, more comfortable, limit exposure to harmful chemicals, and breathe better than synthetic materials.
Ensure that the sleepwear has strong seams that aren’t falling apart or have any loose strings and look for easy-to-use fastenings like snap buttons or zippers for a secure fit. A few recommended brands for safe, comfortable, and practical baby sleepwear include Burt’s Bees Baby, Hanna, HonestBaby, Goumi Kids, and Little Sleepies.
