What are the 5 S's?
The 5 s's stand for swaddling, side or stomach position, shushing, swinging, and sucking. All of these help your baby calm down.
Swaddling
Swaddling means wrapping your baby snugly in a blanket. But it is not just wrapping them. Their arms should be kept close to their body. It helps create a sense of security, which can help babies relax and settle more easily. It also has the additional benefits of preventing sudden movements that could startle your baby and wake them up.
Side or Stomach Position (For Calming Only)
Holding your baby on their side or stomach can help calm them when they are fussy. This position can reduce crying and make them feel more at ease.
But there is something to always keep in mind. It is only for soothing your baby while you are holding them. Never let your baby sleep in these positions, as that is unsafe. It can lead to sudden unexpected infant death (SUID).
Shushing
Babies find a steady shushing sound very soothing. The sound should be consistent and a bit louder than their crying at first. Then you should soften it as they calm down. You can use a white noise machine so that you do not have to create the sound manually, especially if you are already exploring how sound machines can help with newborn sleep issues at home.
Swinging or Gentle Rocking
Gentle, rhythmic movements, like rocking, swaying, or lightly bouncing, helps calm a baby down. Make sure to support their head and neck when you do this to keep them safe.
The motion should be small and steady. Avoid going fast or jerky. You can also use baby swings to take breaks. They mimic your natural movements to soothe your baby.
Sucking
Sucking is naturally calming for babies. That is why offering a pacifier or feeding them when they are upset is helpful. Even if they are not hungry, the act of sucking can help reduce fussiness and promote relaxation.
Benefits of the 5 S's
The obvious benefit of the 5 s's is its calming effect. It helps stop your baby from crying, which is good for their mood. But the 5 s's also have other key benefits that are not as obvious. Here they are:
- Adjusting to the "Fourth Trimester" - The 5 s's let you re-experience while they are in your womb, now that they are outside. It helps them adjust to their new environment.
- Baby Sleep Quality Improvement - A calm baby gets better and longer sleep. The 5 s's can extend your baby's sleep by 30 - 45 minutes.
- Reduce Stress and Pain - Some parts of the 5 s's can help reduce stress and pain. Sucking, for example, can lower heart rates, reduce stress levels, and even equalize ear pressure.
- Calmer and More Confident Parent - If you can calm your baby quickly, you will feel accomplished. You know you are doing the right thing. That can empower you and make you feel more confident.

Where the 5 S's Come From?
Almost all of the 5 s's came from the sensations a baby feels while they are in the womb. Swaddling replicates the snug feeling. Shushing recreates the sounds inside the womb. Swinging is a callback to the way they swayed when their mother was walking.
Swadlling
Inside the womb, babies are held closely with very little room to stretch or move freely. A proper swaddle recreates this same close fit, helping them feel contained and secure.
Side or Stomach Position
Holding your baby on their side or stomach reminds them of their position in the womb. They spent months in these positions. Again, that familiarity will help calm them down.
Shushing
It is not silent inside the womb. The sound of your heartbeat and blood flow is all that your baby could hear. Shushing can help you replicate that. For the best results, you should use baby sound machines.
Swinging
Your baby has experienced swinging motions when they were still in the womb whenever mom walked. That is why swinging is also effective at calming them down. You can use electric baby swings to free a hand or both hands.
Sucking
Sucking is the only one in the 5 s's that does not have a womb origin. However, experts have found that it helps lower heart rate, blood pressure, and stress.
The Foundation: Understanding the "Fourth Trimester"
| Trimester | First trimester | Second trimester | Third trimester |
| Months | 0 - 3 months | 3 - 6 months | 6 - 9 months. |
Everything feels unfamiliar to newborns. They spend the first three months of their lives learning about the world around them. This stage is what people call the "fourth trimester." The 5 s's help bridge this gap by using familiar womb-like sensations.

How To Swaddle a Baby
Please do not swaddle your baby once they show signs of rolling. Using a product like the Momcozy Easy Swaddle Wrap can simplify this process, especially for parents who are still learning how to swaddle a baby safely and get a snug fit without making it too tight.
- Fold your blanket in half diagonally to make a triangle. Lay your baby in the center.
- Lay your baby's right arm flat and bring the left side of the swaddle across the chest.
- Fold the bottom part of the swaddle up and over the feet.
- Repeat for the left arm with the right side of the swaddle.
Calming a Baby By Holding Them in Side or Stomach Position
Pick them up and place them on their left side or stomach while gently rubbing their back. If your baby falls asleep, immediately place them on their back on a flat, firm surface.
Using Sound Machines for Shushing
The Momcozy Baby Sound Machine is a good choice, offering 34 different sounds and app control to ensure a consistent, soothing rumbly noise.
Manual and Automated Swinging
Swinging can be tiring. You can automate it with Momcozy Baby Swings, which feature a 5-point harness and a sturdy base to keep your baby safe.
