As a new parent, you might be wondering what your 3-month-old baby should wear to sleep. It's important to remember that your baby's sleepwear should be comfortable and safe. The ideal room temperature for a baby's room is between 68° and 72°F, and you should dress your baby with one additional layer than you would wear yourself. Generally, a two-piece cotton PJ set or a footed onesie with a muslin swaddle should be enough. However, it's important to avoid overdressing your baby, as overheating has been linked to an increased risk of Sudden Infant Death Syndrome (SIDS). It's also crucial to keep loose items, such as blankets, hats, and toys, away from your baby's sleep area. Swaddling can be a good option for newborns, but it should be discontinued once your baby starts rolling over, which usually happens around the three-month mark. Instead, you can use a sleep sack or wearable blanket to provide extra warmth without restricting your baby's arms.

What You'll Learn
Dressing your baby for the temperature
The temperature of your baby's sleeping environment is an important consideration for their comfort and safety. The ideal room temperature for a baby to sleep in is between 68°F and 72°F (20°C - 22°C). If the room is too warm, your baby may overheat, which has been linked to an increased risk of Sudden Infant Death Syndrome (SIDS). If the room is too cold, your baby may not sleep well.
When dressing your baby for sleep, a good rule of thumb is to put them in one additional layer than you would wear yourself in the same environment. For example, if you're wearing a t-shirt and a sheet, your baby might wear a onesie and a lightweight swaddle or sleep sack. If you're wearing flannel pyjamas under a heavy comforter, your baby might wear fleece-footed pyjamas and a sleep sack or swaddle. It's important to assess your baby's temperature by feeling their core (their chest, neck, back, and tummy). If their core feels warm but not sweaty, and not cold, then they are likely dressed appropriately for the temperature.
It's also important to consider the time of year and the climate you live in when dressing your baby for sleep. For example, if you live in a warm climate like Arizona, your baby may only need to wear a zippered sleeper or a short-sleeved onesie and a lightweight sleep sack, even if the room temperature is outside the recommended range. Conversely, if you live in a cold climate, your baby may need to wear warmer clothing like a long-sleeved onesie and a sleeping bag, or fleece-footed pyjamas with a blanket on top.
As your baby grows and develops, you will also need to adjust their sleepwear. For example, swaddling can be a great way to keep a newborn baby warm and snug, but it can become a safety hazard once they start to roll over, which typically happens around 2 to 3 months of age. At this point, the American Academy of Pediatrics (AAP) suggests using a sleeveless wearable blanket or sleep sack to keep the baby warm while leaving their hands free to assist in rolling. It's also important to note that blankets are not recommended for babies under 12 months of age, as they can pose a suffocation risk.

Using a swaddle or sleep sack
Swaddling is when you wrap your baby so they are warm, snug, and feel like they're back in the womb. It helps to prevent the Moro reflex, which causes their arms and legs to jerk and flail, startling them awake. However, swaddling can be cumbersome, especially during nighttime diaper changes, and it may restrict your baby's movement, affecting hip development if wrapped too tightly. It is generally recommended to stop swaddling when your baby is 2 months old or starts attempting to turn over.
Sleep sacks are wearable blankets that zip up and have holes for arms. They are designed to help babies feel calm and secure, which prepares them for sleep. They can be used from birth and are safer than blankets, as they don't pose a suffocation risk. Sleep sacks are also more convenient than swaddles, especially when your baby starts rolling over, and they can be used for longer—even once your baby has transitioned to a big kid bed. However, it's important to ensure that the sleep sack fits your baby well, so they don't slide down inside it during the night.
The ideal room temperature for a baby is between 68° and 72°F (20° to 22°C). You can dress your baby for sleep based on what you're wearing. If you're wearing flannel pyjamas under a heavy comforter, your baby might wear a onesie and a lightweight swaddle or sleep sack. If you're wearing a t-shirt and a sheet, your baby might only need a onesie and a lightweight sleep sack. Feel your baby's core (chest, neck, back, and tummy) to check if they're warm but not sweaty, and slightly underdressed rather than heavily overdressed.
According to the American Academy of Pediatrics (AAP), babies should sleep in their own crib or bassinet in the same room as their caregiver for the first 6 to 12 months to reduce the risk of SIDS. It's important to avoid loose items in the crib, such as hats, mittens, hair bows, or pacifier clips, as these can be unsafe during sleep.

The risks of co-sleeping
When putting a 3-month-old baby to sleep, it is generally recommended to put them in one additional layer than you would wear at night. This could be a two-piece cotton pyjama set or a footed onesie plus a muslin swaddle. It is important to keep the ideal room temperature between 68° and 72°F (20° to 22°C) and to avoid overdressing the baby, as overheating has been linked to Sudden Infant Death Syndrome (SIDS). Loose items and clothing, such as hats, mittens, hair bows, and pacifier clips, are not considered safe for sleep as they can cover the baby's face and increase the risk of SIDS. Instead of using a blanket, you can use a swaddle or sleep sack to keep your baby warm. It is recommended to stop swaddling once the baby shows signs of wanting to roll over, which can happen as early as 3 to 4 months old.
While co-sleeping can have its benefits, such as convenience for breastfeeding and promoting a stronger bond between the parent and child, there are several risks associated with it, especially with infants under 12 months old. Here are some of the risks of co-sleeping:
- Increased risk of SIDS: Several studies have found that bed-sharing substantially raises a baby's risk of SIDS, especially in the first 12 months of life. The Western bed was not designed with the infant in mind, and babies may not be able to free themselves from heavy bedding or adult bodies, increasing the risk of entrapment and suffocation.
- Unsafe sleeping environment: Co-sleeping can create an unsafe sleeping environment for the baby. Loose materials, such as weighted blankets, stuffed animals, and other loose objects, can cover the baby's head or trap their body, increasing the risk of suffocation and strangulation.
- Difficulty establishing independent sleep: Babies who co-sleep may associate sleep with being close to their parents and in their bed. This can become problematic when parents try to transition the baby to sleep independently in their own bed.
- Disturbed sleep for parents: As children get older, co-sleeping may cause more disturbances to the parents' rest. It is important for parents to get adequate, uninterrupted sleep to function properly.
- Negative impact on social behaviour and cognitive abilities: While more research is needed, some studies suggest that co-sleeping may negatively impact toddlers' social behaviour and cognitive abilities.
It is important to note that room-sharing, where the baby sleeps in the same room but on a separate surface close to the parent's bed, is recommended for the first 6 months of a child's life as it can reduce the risk of SIDS by up to 50%. This allows for the benefits of proximity, such as easier breastfeeding and increased parental awareness, while providing a safer sleeping environment for the baby.

The ideal room temperature
To check if your baby is too hot, feel their chest or the back of their neck. Their hands and feet will usually be cooler, which is normal. If your baby's skin is hot or sweaty, remove one or more layers of bedclothes or bedding.
It is recommended that a baby wears one extra layer of clothing than an adult would wear in the same environment. For example, if you are wearing a t-shirt and a sheet, your baby might need a sleep sack or swaddle. Sleep sacks are a good investment as they act as a sleep cue and keep your baby warm without loose blankets.
It is important to avoid covering a baby's face and head when they sleep. Babies regulate their temperature through their head and face, so covering these areas can increase the risk of overheating. Hats, beanies, hair bows, and pacifier clips are not considered safe for sleep.
You can also use a room thermometer to help maintain the ideal temperature. Some video monitors come with built-in thermostats to help you track temperature and humidity.

Signs your baby is cold
The ideal room temperature for a baby should be 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 to sleep. For example, if you wear a t-shirt and a sheet, your baby might wear a onesie and a lightweight swaddle or sleep sack. If you are comfortable, your baby is likely comfortable too. You can also feel your baby's core (their chest, neck, back, and tummy) to check if they feel warm but not sweaty, or cold.
- Your baby is crying. Babies are more likely to cry if they are cold at night than if they are hot. They are also more likely to wake up or be fussy if they are cold.
- Your baby is uncomfortable. If your baby is too cold, they will likely be uncomfortable.
- Your baby has cold hands. Young babies have underdeveloped circulatory systems, and their bodies regulate temperature differently than adult bodies. However, cold hands do not necessarily mean that the whole body is cold.
- Your baby is sweating. Too much moisture can lead to prickly heat, so if your baby is sweating, take off a layer or change their clothes so more air can flow over their skin.
- Your baby is wearing too few layers. Dressing your baby in too few layers can lead to more frequent wake-ups.
It is important to create a safe sleeping environment for your baby. Do not use any loose bedding in your baby's crib for the first year, such as blankets, quilts, or stuffed animals. These can cause accidental suffocation or overheating, increasing the risk of sudden infant death syndrome (SIDS). Instead, use a sleep bag or swaddle with an appropriate TOG rating to maintain your baby's comfort temperature.

Sleep sacks (also known as wearable blankets) are like sleeping bags that provide an extra layer of warmth without restricting a baby's arms. They can be used from birth until your child grows out of them. The American Academy of Pediatrics (AAP) recommends sleep sacks as a safer alternative to loose blankets and sheets for babies under 12 months old.
Yes, the AAP recommends room-sharing without bed-sharing for at least the first 6 months, as this can reduce the risk of SIDS. It's also important to use a firm, flat sleep surface and to keep soft toys, pillows, blankets, and other loose items away from your baby's sleep area.
Infants up to 3 months old should get 14-17 hours of sleep over a 24-hour period, according to the National Sleep Foundation. They may take 2-3 naps during the day and then sleep for a longer stretch at night after a late-night feeding.
