Why it’s important to know how to dress baby for sleep in winter

Many first-time parents wonder why so much emphasis is placed on sleep outfit selection. There is a great reason for this and it relates to your baby’s health and safety. Babies can’t regulate their body temperatures as effectively as older children and adults. This is because a newborn's body surface-to-weight ratio is about three times greater than an adult’s. This means that they can both lose heat and overheat very quickly. This is especially true if your little one was born prematurely or at a low birth weight. However, even full-term newborns are unable to maintain their body temperature if the environment around them is too hot or too cold. In fact, they lose body heat about four times faster than adults! What’s more, they’re unable to shiver like we do to increase their body temperature when it drops below the normal range. When this happens, it can impact their breathing and their body’s use of oxygen. That’s why it’s so important to know how to dress baby for sleep in the summer and winter months. 


What temperature should a baby’s room be?

The ideal temperature for baby’s room may vary slightly from one child to another. These variations relate mostly to what type of climate your newborn is accustomed to. However, although there may be slight differences in the ideal temperature for a baby’s room, it’s recommended that nursery rooms are kept between 68 to 72 degrees Fahrenheit or 20 to 22 degrees Celsius. This temperature range is ideal because it helps your little one maintain a healthy body temperature and allows them to sleep peacefully while still waking up to auditory signals. This helps decrease the chance of Sudden Infant Death Syndrome (SIDS).

How to dress baby for sleep in winter

If you’re wondering how to dress a newborn in winter, you’re not alone. Many new parents are unsure what sleepwear is appropriate for their little ones as the temperature begins to drop outside. Here are a few key things to keep in mind: 


  • Dress your baby for the temperature indoors, not the temperature outdoors. Many parents think that because it’s cold outside they should bundle their little one up for sleep, but this can result in overheating. 
  • A good rule of thumb to help guide you when you’re dressing your baby for sleep is to add one extra layer of clothing more than you would typically wear in the same temperature.
  • If the temperature in your little one’s room is dropping overnight, add one extra layer to help them stay warm. This could be a sleep bag or a swaddle. You could also try out pajamas with covered feet. If you’re adding one more layer of clothing than you normally would, keep an eye out for any signs that your baby is overheating. 
  • Keep in mind that it’s better to have your baby slightly underdressed, rather than heavily overdressed, so don’t add more than one layer at a time. 
  • Make sure you have a thermometer in your baby’s room, so you can get a sense of how the temperature is fluctuating overnight and whether or not your heating or cooling system is maintaining a steady climate. 
  • Skip the hat, even in the winter months. Putting a hat on your little one overnight can be a safety hazard, as it can easily slip off your baby’s head. It may also contribute to overheating.
  • Remember, you know your baby best and every child is different. Use your judgment when dressing your little one for bed. 

How do I know if my baby is too warm? 

The best way to determine if your child is overheating is to take their temperature. There are also a number of other easy-to-spot signs you can look for. Here are some key indicators that your baby is overheating: 


  • They feel warm to the touch 
  • Their skin is red or flushed 
  • They’re nauseous or vomiting 
  • They have an elevated heart rate 
  • They’re acting tired or sluggish
  • They appear to be confused, disoriented, or dizzy 
  • They’re sweating or have damp hair

What should I do if I think my baby is overheating?

If you’re worried that your baby is overheating, there are a few things you can do to help reduce their body temperature:


  • Remove your baby’s clothing 
  • Take them to a cooler location if possible 
  • Offer your baby fluids (breastmilk, formula, or a glass of water if they’re old enough) 
  • Give your baby a sponge bath with lukewarm water

How can I tell if my baby is too cold? 

Just like overheating, babies show signs of distress that are easy to spot when the temperature in their nursery is too low. A baby who’s too cold will give you some warning signs that their body temperature is not quite right. 


Here are some key indicators that your baby’s body temperature is dropping below a normal range: 


  • They become sluggish or unresponsive
  • Their cry is weaker than usual 
  • Their skin is pale and cold to the touch 
  • They’re having trouble breathing
  • They’re not feeding 

What should I do if I think my baby is too cold?

If you suspect that your baby is too cold, here are a few things you can do right away to try and warm them up:


  • Add additional warm layers of clothing
  • Use your own body heat by holding your baby close to you. You can also drape a blanket over them, but never leave them unsupervised with the blanket.
  • You may also want to try swaddling your baby

Frequently Asked Questions

Your baby may wake up if the temperature in their room becomes too cold. If your little one is waking up frequently throughout the night during the winter months, you may want to check if the temperature in their nursery drops as it gets colder outside.

Your baby may become fussy and cry if they’re too hot or too cold. However, it’s important to note that some babies will become more sluggish and/or unresponsive when they’re either too hot or too cold. So it’s crucial to keep an eye out for both types of behavior when monitoring your baby’s temperature.

Your baby may be okay in just a diaper underneath their swaddle if their nursery is warm enough. If it’s cooler in your nursery or outside, it’s probably best to dress your baby in a short or long-sleeved onesie to ensure that they’re warm enough. However, it’s also important to ensure they don’t overheat, so keep an eye out for sweating and flushed or hot skin.

Like most things related to parenting, there’s not an easy answer to this question. Swaddling is a practice that has been used in many cultures for centuries. So, it comes as no surprise that it certainly has its benefits. However, there are also some risks and drawbacks. Here are a few things to consider when deciding what is best for you and your baby:

Swaddling may help your baby sleep for longer periods of time uninterrupted
Swaddling may also help soothe your baby if they’re feeling fussy as baby swaddle wraps tend to mimic the environment they experienced in the womb
Swaddling may increase the risk of hip dysplasia (essentially, improper development of the hip joint) if the swaddle is too tight or the baby spends too much time swaddled.

While a onesie is likely not going to be warm enough for sleep on a winter night, if your newborn seems comfortable during the warmer months, it’s absolutely fine to let them sleep in just a onesie. However, because babies lose body warmth much faster than older children and adults, they’ll likely prefer having a light layer even on warm days. A good rule of thumb for parents who are concerned about properly dressing baby for sleep is that your newborn probably needs one more layer of clothing than you would think in order to be comfortable.
