You may have heard that the best weighted baby sleep sacks may help your baby fall asleep faster, and stay asleep longer. But what is a weighted sleep sack and what is the science behind this? Read on to learn more about why weighted sleep sacks work so well for babies.
Function
Many parents have turned to baby sleep sacks as a safe and cozy alternative to loose bedding and loose blankets. These wearable blankets help reduce the risk of sudden infant death syndrome (SIDS). Can a weighted baby sleep sack add additional advantages?
Weighted sleep sacks are infant sleep clothing that provide deep pressure stimulation (DPS) which helps babies relax, and helps them fall asleep easier. DPS works by providing a gentle hug-like sensation over the entire body.
This is similar to swaddling or being in the womb, which creates feelings of comfort and security. This sensation is made even stronger with weighted sleep sacks because they are filled with small beads that provide extra weight and pressure, mostly on baby's chest. Weighted blankets are great alternative for older children.
Science
The science behind this is as follows. When we experience DPS, our bodies release hormones like serotonin, endorphins, and oxytocin. All these hormones help us relax and feel calm. Studies have shown that using a weighted sleep sack can decrease fussy behavior in babies, as well as reduce their levels of cortisol (the stress hormone).
It also promotes a better quality of sleep since the baby feels secure and comfortable in the sack throughout the night.
Another benefit of using the best weighted sleep sack is that it can help regulate your baby’s temperature while it is sleeping. The fabric used in these sacks is usually breathable and lightweight.
This allows for natural airflow without letting cold air in or trapping heat inside. This helps keep your baby at a comfortable temperature throughout the night without the risk of overheating or getting too cold.
Pros & Cons
There are both pros and cons to using a weighted sleep sack with your baby. Here are some of the benefits and drawbacks you should consider:
Pros
Weighted sleep sacks can help babies feel safe, secure, and calm during their sleep. They may also improve sleep quality and duration. Additionally, they are versatile and can be used both at home and while traveling.
Cons
Weighted sleep sacks might not be suitable for all babies – they may be too heavy or uncomfortable for some babies. It also takes time to get used to the sensation of a weighted blanket so it’s important to ensure your baby is adapting well. Finally, these products are more expensive than regular blankets so there is an additional financial cost.
Difference Between A Swaddle And A Weighted Sleep Sack
Weighted sleep sacks and swaddles are both popular products used to help babies feel secure, safe, and relaxed during sleep. Yet there are differences between the two that parents should consider.
Swaddle
A swaddle is a type of wrap for babies that helps them feel comfortable and secure, encouraging better rest at night. Swaddles come in various materials like muslin, jersey, silk, organic cotton, and more. They usually have velcro fasteners which allow you to adjust the snugness as your baby grows. You should stop swaddling your baby when they start to roll over. That's typically between two and four months.
Weighted Sleep Sack
A weighted sleep sack is essentially a blanket with added weight to simulate a calming sensation. It’s usually made of cotton or bamboo and filled with plastic pellets or glass beads. It’s designed to be worn during the day and at night to help develop healthy sleeping habits. You can start using a weighted sleep sack from four months up to two years of age.
These two products complement each other well, as you can smoothly transition your baby from a swaddle to a weighted sleep sack.
Tips
Using a weighted sleep sack correctly and taking into account safety considerations can be beneficial for your baby's sleep and development. Here are some tips to ensure success:
Wear it during the day: Babies should wear weighted sleep sacks throughout the day, not just at night. This imprints a calming sensation that can carry over into the nighttime.
Start early: To get maximum benefit, start using a weighted sleep sack when your baby is around 3–6 months old. That’s when your baby starts separating day from night and developing healthy sleep habits.
Choose comfort: Comfort is key in helping babies feel safe and secure while they learn how to settle themselves at night. Pick fabrics with natural fibers like cotton or bamboo as these are gentle against your baby’s skin and breathable too.
Consider weight: Weighted sleep sacks come in many different weights. They should never weigh more than 10% of your baby's body weight! If you are unsure it is safer to chose a non weighted sleep sack.
Parents who practice bed sharing should be particularly cautious when considering weighted sleep sacks. A baby should have their own designated sleep surfaces, separate from adult bedding. This is important to minimize the risk of suffocation or overheating.
Conclusion
Weighted sleep sacks are an effective way to help your little ones feel secure and comfortable while they rest. They provide deep pressure stimulation which helps babies relax.
DPS releases hormones that make them feel calm and safe while they drift off into dreamland. Plus, they keep your baby at a comfortable temperature throughout the night so you don’t have to worry about them getting too hot or cold.
