Swaddling is a traditional technique used to help newborns sleep. It involves wrapping a baby in a lightweight cloth or blanket to restrict their movement and recreate the confined space of the uterus. Swaddling is thought to promote better sleep by providing a sense of comfort and security, reducing unexpected awakenings caused by the startle reflex, and keeping the baby warm. However, there are differing opinions on whether swaddling is necessary or beneficial for newborns, with some studies suggesting potential risks associated with the practice, such as an increased risk of hip problems and sudden infant death syndrome (SIDS) when babies are placed on their sides or stomachs while swaddled.

Swaddling can help your newborn sleep better
Swaddling is a parenting technique that has been used for a long time. It involves wrapping a baby in a blanket to restrict their movement and is thought to recreate the confined space of the uterus, helping them settle into sleep.
Some studies have shown that swaddled babies wake less frequently and sleep longer than non-swaddled babies. It is also believed that swaddling can help reduce the risk of sudden unexpected deaths in infancy (SUDI) and sudden infant death syndrome (SIDS) by keeping babies on their backs during sleep. However, it is important to note that one study published in the journal Pediatrics found that when swaddled babies were placed on their sides or bellies, their risk of SIDS increased significantly, especially for babies over six months old.
It is recommended to stop swaddling as soon as babies show signs of attempting to roll onto their tummies, as this can increase the risk of suffocation and restrict their movement, which is important for healthy development. Additionally, it is crucial to ensure that the baby's face and head are always uncovered during swaddling to prevent overheating and breathing difficulties.

It is important to know when to stop swaddling
Swaddling is a great way to help your newborn settle and sleep, and it can be continued as long as your baby is not showing signs of rolling over. Once your baby can roll onto their tummy, it is unsafe to be swaddled as they need their hands free to push up from the mattress.
The American Academy of Pediatrics (AAP) states that swaddling, when done correctly, can be an effective technique to calm infants and promote sleep. It is thought that swaddling helps recreate the restricted space of the uterus, providing a sense of security and comfort. However, as your baby grows and becomes more mobile, swaddling can become a safety hazard.
Most babies will be ready to come out of the swaddle between 2 and 4 months old. According to the AAP, babies typically start to roll around 3 to 4 months of age. If your baby is in this age range but not yet showing signs of rolling over, there is no immediate need to stop swaddling. However, it is essential to monitor their development closely and stop swaddling as soon as they start attempting to roll.
Some babies may show signs of rolling earlier, around 8 weeks, which would indicate that it's time to transition out of swaddling. It is important to follow your baby's lead and adjust their sleep routine accordingly. If you notice your baby breaking out of the swaddle or showing signs of overtiredness, it may be time to transition to a different sleep method.
There are a few gradual ways to transition out of swaddling. One method is to start by swaddling your baby with one arm out of the swaddle for a few nights. Once they adjust to having one arm free, you can move on to swaddling with both arms unrestrained. After a few more nights, you can stop using the swaddle blanket altogether and transition to a sleep sack or a lightweight wearable blanket.

The right material for swaddling
Breathability and Softness:
Choose a fabric that is soft, breathable, and lightweight, such as cotton or bamboo. Cotton muslin is a popular choice due to its softness, durability, and breathability. It gets softer with use and washing, ensuring your baby's comfort. Bamboo, often blended with cotton, offers antimicrobial and moisture-wicking properties, keeping your baby's skin fresh and regulating their temperature.
Stretch and Structure:
Consider the stretch and structure of the fabric. For example, jersey swaddles, typically made from cotton blended with rayon or polyester, offer a stretchy and silky soft option. They provide more structure, helping to keep your baby in the proper swaddle position.
Safety Considerations:
Prioritize safety by avoiding fabrics that may cause overheating. Ensure the swaddle is firm but not too tight, and avoid covering your baby's head or face. Some sources recommend avoiding swaddles with velcro or zippers that restrain the baby's arms, as these can be unsafe once the baby starts rolling.
Versatility:
Muslin swaddles are versatile and can be used as stroller covers, nursing covers, or light blankets. They offer adjustability, allowing you to create a custom wrap for your baby. However, swaddles with closures, such as zippers or velcro, are convenient and easy to secure, especially during nighttime changes.
Baby's Preferences:
Remember that each baby is unique, and they may prefer one type of swaddle over another. It may take some time to find the right swaddle that suits your baby's needs. Follow guidelines from reputable sources, such as the American Academy of Pediatrics (AAP), to ensure a safe and comfortable swaddling experience for your little one.

The right technique for swaddling
Swaddling, when done correctly, can be a useful way to help your baby settle and sleep. It is thought that swaddling helps to recreate the restricted space of the uterus, helping a baby to settle into sleep.
- Place a light cotton or muslin blanket on a flat surface, like a changing table or bed, with one corner folded down.
- Lay your baby face-up on the blanket, with their head just above the folded corner.
- Keep your baby’s right arm straight by their side, then wrap the right corner of the blanket over them, pulling it snugly down and across Baby’s body and tucking it under the left side of their bum.
- Bring the bottom corner up over your baby’s feet. Make sure to fold the blanket down if it’s close to their face to prevent any obstruction.
- Wrap the left corner over your baby, keeping their left arm straight down. Only their head and neck should be exposed, making sure the blanket stays snug.
- Finally, check that the swaddle is not too tight around the hips and legs. The wrap must be firm but not too tight.
Some important things to keep in mind:
- Avoid weighted swaddles, as they may place too much pressure on a baby’s chest and lungs.
- Do not swaddle your baby if they share a sleep surface with another person.
- Do not cover your baby’s head or their face. This is to stop the wrap from blocking their breathing and overheating them.
- Prevent overheating by making sure your baby is not overdressed under the wrap.
- Stop swaddling as soon as your baby starts showing signs that they can begin to roll.

Swaddling can be dangerous if not done correctly
Swaddling can be an effective technique to help calm infants and promote sleep. However, it is crucial to follow certain guidelines to ensure the safety of the baby. Here are some important considerations to keep in mind:
Firstly, always place the baby on their back to sleep and never on their side or tummy. This is crucial to reduce the risk of Sudden Unexpected Death in Infancy (SUDI) and Sudden Infant Death Syndrome (SIDS). A study published in the journal Pediatrics found that the risk of SIDS significantly increased when swaddled babies were placed on their sides or bellies, especially for babies over six months old.
Secondly, ensure that the baby's face and head are uncovered during swaddling. This is important to prevent the wrap from blocking their breathing and overheating them. The wrap should be firm but not too tight, and it should only cover the baby's body, not their neck or head. Overheating can also be prevented by making sure the baby is not overdressed under the wrap. In warm weather, a baby may only need a nappy and a lightweight wrap.
Thirdly, stop swaddling as soon as the baby starts showing signs of rolling or attempting to roll onto their tummy. This is because swaddling can restrict the baby's movement and may cause issues with their hip development if continued for too long. Additionally, once the baby can roll, they may be able to turn onto their tummy while swaddled, increasing the risk of SIDS.
Furthermore, never use swaddles with velcro or zips that restrain the baby's arms. Instead, use lightweight cotton or muslin wraps. Avoid using rugs or thick blankets as they can cause overheating.
Lastly, if someone else is looking after your baby, ensure they are aware of safe swaddling practices and always follow safe sleep recommendations.
