Ensuring that your baby is sleeping in a safe position is crucial for their well-being and your peace of mind. The American Academy of Pediatrics (AAP) recommends room-sharing without bed-sharing for at least the first six months, as this period carries the highest risk of Sudden Infant Death Syndrome (SIDS). The safest sleep position for a baby is on their back, which has been proven to reduce the risk of SIDS. While side sleeping is generally considered safe after 4-6 months when babies can roll over independently, it is not recommended for infants under one year old. Here's everything you need to know about sleep positions for your 3-month-old baby.

What You'll Learn

The safest position for a 3-month-old to sleep is on their back
Sleeping on their back is also beneficial for a 3-month-old's development. At this age, babies are still developing their neck muscles and sleeping on their back provides better support for their necks and heads. Sleeping on their side can increase the risk of neck conditions such as torticollis, or "wry neck", which can affect their sleep and comfort. By placing them on their back, you reduce the risk of neck problems and promote healthier growth and development.
Additionally, sleeping on their back can help regulate a 3-month-old's temperature. Overheating is a concern for young babies, and by sleeping on their back, air can circulate more freely, reducing the risk of overheating. It is important to ensure the room temperature is comfortable and to dress the baby in light clothing to prevent them from getting too warm during sleep.
While sleeping on their back is the recommended position, it is important to also consider the sleep environment. The crib or bassinet should be kept clear of any toys, blankets, pillows, or other objects that could pose a suffocation risk. It is also crucial to avoid bed-sharing during the first six months, as advised by the AAP, as this can increase the risk of SIDS. Instead, room-sharing is recommended, where the baby's crib or bassinet is placed in the same room as the caregiver.
In summary, the safest position for a 3-month-old to sleep is on their back. This position reduces the risk of SIDS, supports healthy neck development, helps regulate temperature, and provides a safer sleep environment. By following this recommendation and creating a safe sleep space, caregivers can promote the well-being and safety of their 3-month-old during sleep.

Room-sharing without bed-sharing is recommended for at least the first 6 months
When it comes to sleep positions for a 3-month-old, it is recommended that they sleep on their back. Side sleeping is generally not advised for babies under 1 year old, as it can increase the risk of sudden infant death syndrome (SIDS) and other issues like 'wry neck'.
Room-sharing allows for easier feeding, comforting, and monitoring of the baby during the night. It also helps support breastfeeding and can reduce the risk of SIDS by as much as 50% in the first 3 months. However, it is important to maintain a safe sleep environment, even when room-sharing. Avoid using soft bedding, such as crib bumpers, blankets, pillows, and soft toys. The crib should be bare, and the sleep surface should be firm and flat with a tight-fitting sheet.
Additionally, it is recommended to avoid exposing the baby to smoke, alcohol, and illicit drugs. Dress the baby in light clothing, and prevent them from overheating by maintaining a comfortable room temperature. It is also important to note that the benefits of room-sharing may diminish if it leads to bed-sharing or if safe sleep practices are not followed.
While room-sharing can be beneficial for the first 6 months, it is important to gradually transition the baby to their own room eventually. This transition can be made easier by practicing naps in the nursery, establishing daily routines, and maintaining a consistent bedtime routine.

Avoid side sleeping as it increases the risk of SIDS
When it comes to putting your 3-month-old baby to sleep, it is recommended that you place them on their back. Sleeping on the back is proven to be the safest position for babies and can prevent sudden infant death syndrome (SIDS).
The American Academy of Pediatrics (AAP) advises against side sleeping for babies as it offers no benefits and is not considered safe. Side sleeping can increase the risk of SIDS because it is easier for the baby to accidentally roll over onto their stomach. When babies are younger than 4 months old, they are often too small to support their head or change positions, increasing the risk of suffocation.
Additionally, sleeping on their side can cause a condition called torticollis or "wry neck," which occurs when the baby's neck and head are not adequately supported. It can also lead to a flattened or oddly shaped head, known as plagiocephaly, due to the softness of their skulls and weak neck muscles at this age.
To ensure your baby's safety, always place them on their back to sleep and avoid bed-sharing. Room-sharing without bed-sharing is recommended by the AAP for at least the first 6 months, as it helps with feeding, comforting, and monitoring your baby while reducing the risk of SIDS.
If you notice your baby prefers side sleeping or has a flat head, consult your baby's pediatrician for advice.

Keep the crib clear of toys, blankets, and pillows
When putting a 3-month-old baby to sleep, it is important to place them on their back in their crib. This sleep position has been proven to prevent sudden infant death syndrome (SIDS). The chances of SIDS are highest for infants between 1 and 4 months old, so it is crucial to keep the crib clear of any objects that could increase the risk of SIDS or accidental suffocation.
The American Academy of Pediatrics (AAP) recommends keeping the crib bare, meaning nothing should be in the crib with the baby until they are at least 12 months old. This includes blankets, toys, bumpers, pillows, and other soft items. These items can pose a risk of suffocation or accidental injury. Instead of a blanket, a sleep sack can be used to regulate the baby's body temperature and keep them comfortable while sleeping.
It is also important to ensure that the crib is free of any loose items or hazards that could potentially harm the baby. This includes items such as crib bumpers, stuffed animals, and other toys. Even devices made specifically for babies, such as car seats, carriers, swings, and strollers, are not recommended for regular sleep. If a baby falls asleep in one of these devices, it is best to move them to a firm mattress as soon as possible.
Additionally, bed-sharing with a baby is not recommended, especially before the age of 4 months, as it can increase the risk of SIDS. Instead, room-sharing is advised, where the baby's crib or bassinet is placed in the same room as the caregiver, allowing for easy feeding, comforting, and monitoring during the night.
By following these guidelines and keeping the crib clear of toys, blankets, pillows, and other objects, you can help create a safe sleep environment for your 3-month-old baby and reduce the risk of SIDS and accidental injuries.

Dress the baby in light clothing, not heavy layers
It is recommended that 3-month-old babies get 14–17 hours of sleep over a 24-hour period. The American Academy of Pediatrics (AAP) recommends room-sharing without bed-sharing for at least the first 6 months or, ideally, until a baby's first birthday. This is because the risk of SIDS (sudden infant death syndrome) is highest during this period.
To reduce the risk of SIDS, it is recommended that babies are dressed in light clothing rather than heavy layers. Overheating has been linked to a greater risk of SIDS, especially during the first six months. A baby should be dressed in layers of fitted clothing so that layers can be added or removed as the temperature changes. On warm nights, a short-sleeve cotton or organic-cotton bodysuit or T-shirt with a muslin or cotton swaddle or sleep sack is appropriate. On colder nights, a pair of snug-fitting fleece pyjamas or a heavier microfleece swaddle or sleep sack over standard cotton pyjamas is suitable.
Babies should not be dressed in loose clothing or accessories, such as hats, as these can cover their faces, inhibiting free breathing. It is also important to avoid using blankets, pillows, or other objects in the baby's sleeping area, as these can also cover the baby's face and restrict breathing.
In addition to dressing the baby in light clothing, it is recommended that the baby's sleeping environment is well-ventilated and not too warm. A home thermostat or indoor thermometer can help ensure the room is at a comfortable temperature.
