Should the baby have a sleep sack?

  The baby sleep sack is a popular and necessary baby item. Most mothers all over the world are using them. Why a baby needs a sleep sack? How to wear a sleep sack? With doubt, with a thought, let us learn more for answers.

  There are many different types of sleep sacks on the market, including the sleep sack with legs, the sleep sack with sleeves, a long sleeve sleep sack, a sleeveless sleep sack, etc.

1. Why the baby needs a sleep sack?

    • baby needs a safe feeling

      Babies, especially newborns, have not been in the new world for a long time. The mother’s womb is a safe place for them. They love to be snuggled and swaddled. A suitable sleep sack can give them a safe of security and help them feel warm and cozy. And sometimes, babies may have a startle reflex during sleep that will wake them, make them scared, and cry. A baby sleep sack with an anti-startle reaction is helpful to solve this problem. Mothers can consider buying one.

    • help baby sleep safe and better

      In the days before baby sleep sacks, parents usually cover the baby with a quilt or a blanket. Babies are easy to kick the quilt when they sleep. And then they catch a cold the next day. Besides, there is a further concern, and the baby may suffocate if the quilt or blanket is over his face.

      Sleeping in sleep sacks can help keep out of the above dangers. Babies can sleep safer and better.

    • an excellent warm keeping

    The sleep sack is kind of womb-like and cozy for the baby. They can have a more peaceful, restful sleep in it. Sleep sacks have different TOGs. The higher TOG is, the warmer the sleep sack can be. Mothers always will choose a 2.5 TOG or 3.5 TOG sleep sack for babies in winter. And these sleep sacks also have fold-over cuffs and footies. Babies can hide their hands and feet in it to get more warmth.


    • decrease the risk of SIDs

      SIDs is sudden infant death syndrome. The risk of swaddling, as I mentioned above, if you use the quilt to cover your baby at night, his mouth and nose may be covered. And your baby is with no ability to push himself away from the danger at this age.  

      Therefore, choosing a suitable sleep sack will greatly reduce the chances of danger to the baby and allows parents to sleep peacefully.

      It is worth mentioning that the baby mattress must be slightly hard. And you should keep the crib clean, empty, and without any objects, including pillows and soft toys. It can prevent the baby from the danger of suffocation.

      At the same time, the baby can not turn over by himself. Don’t let your baby sleep on his stomach or side alone.

    • anti-Moro reflex

      What is the Moro reflex?

      The Moro Reflex is a type of infant reflex, which is also known as the startle reflex. When a sudden stimulus occurs, the infant will be scared. His arms will be extended, and his fingers will be spread. Don’t worry, and this reflex will disappear within three to five months.

      After birth, babies come into a new environment. They will feel insecure. And they are easy to wake up. A swaddling sleep sack can help him maintain better sleep quality and make it easier to develop regular sleep.

    The key point of a suitable swaddling sleep sack is to select the right size. It is better to be tight on the top and loose on the bottom.

    2. How to wear a sleep sack?

    Wearing a sleep sack is not very complicated. Usually only need three steps. You can check the details below:

    • Unzipped the sleep sack and place your baby's back in it.
    • Tuck legs inside the sleep sack’s legs. At the same time,tuck arms inside sleeves gently, slowly.
    • Finally, you just need to close the zipper.

    3. When to stop using sleep sacks?

        When to stop using sleep sacks? It depends on babies. Newborns, or when the babies are little, need to find a similar feeling like staying in the womb. Being swaddled can give newborns a sense of security. Newborns usually sleep in the arms-in or arm-up position. These positions can help them feel safe and have a peaceful, restful sleep.

        As time goes by, newborns grow. They don’t like to be swaddled anymore. And they also start to learn to roll and crawl. At this time, parents need to change to other types of sleep sacks for their babies to wear. These sleep sacks need to be relaxed and loose. So babies can kick their legs in it freely without restriction. The older a baby is, the more freedom he wants.

        Most families will stop using sleep sacks when the baby is one or two years old. But there are some babies who will continue to use sleep sacks through their toddlerhood. As long as the size is suitable, toddlers can keep wearing it.
