Getting babies to sleep longer is every parent’s dream. Quality sleep is vital for a baby’s growth and development, helping with everything from brain development to emotional regulation. Swaddling can be an effective way to help a newborn sleep. It feels calm and cozy, mimicking the snug feeling of the womb. It also helps suppress the startle reflex (or Moro Reflex), allowing babies to sleep more soundly.

However, swaddling isn’t a forever solution. As babies grow and develop, they may have started to roll and show other signs that it’s time for him or her to stop being swaddled. Transitioning from a swaddle to a sleep sack can be a smooth process when approached with the right steps. Today, we’re sharing an easy-to-follow guide on how to transition your baby out of the swaddle and into a sleep sack effectively.

When To Transition From Swaddle To Sleep Sack

Knowing when to begin transitioning out of the swaddle is key to ensuring your baby remains safe and comfortable during sleep. The right time to transition can vary. The American Academy of Pediatrics (AAP) recommends to parents that it is time to stop swaddling their infant when they show signs of rolling. Every child is different, but most experts, including pediatricians and sleep consultants, recommend starting the transition when:

  • Your baby shows signs of rolling over independently.
  • Your baby regularly tries to get their arms out of the swaddle.
  • The startle reflex has diminished.
  • Your baby starts resisting the swaddle or shows discomfort.
  • It’s becoming unsafe to keep your baby swaddled, such as when they can wiggle too much.

By observing these signs, you’ll know it’s time to begin the process of transitioning from a swaddle to a sleep sack.

How To Transition From Swaddle To Sleep Sack

Transitioning from a swaddle to a sleep sack can be a stressful and overwhelming endeavor. You may FINALLY be getting quality sleep with your little one in a swaddle. The thought of transitioning them and jeopardizing that sleep can be a depressing thought. 

How To Transition From Swaddle To Sleep Sack

Here’s a step-by-step guide to help you with this transition while ensuring your baby continues to get the restful sleep they need.

Step 1: Choose the Right Sleep Sack

The first step in the process is selecting a suitable sleep sack. Sleep sacks are wearable blankets designed to keep your baby warm and cozy without the risks associated with loose bedding.

  • Look for a sleep sack that fits your baby’s size and stage of development.
  • Ensure it allows for arms free movement, especially if your baby shows signs of rolling.
  • Opt for materials that suit the season (e.g., lightweight cotton for summer, fleece for winter).

One of my personal favorite options is called the Sleeping Baby Zipadee-Zip. The Zipadee-Zip is a starfish designed blanket in an ultra-soft and breathable bamboo fabric. It has a double-zipper for easy and quick diaper changes. For infants who enjoy the feeling of being swaddled, the Zipadee-Zip can be a great option. One of my favorite features of the Zipadee-Zip is that it is wearable for ages 3 months (8 lbs.) to 3T!

Step 2: To Start….Leave One Arm Out

A gradual approach often works best for transitioning out of the swaddle. Start by removing the swaddle from one arm while keeping the other snugly wrapped.

  • Do this for a couple of days or nights to allow your baby to adjust.
  • Observe how they respond. If they sleep well, it’s a good sign that they’re ready to continue.

This “halfway” approach helps babies adjust without fully losing the comfort they’re used to. It can make the transition from swaddle to sleep sack easy and less stressful for both you and your baby. 

Step 3: Transition to Both Arms Free

Once your baby is comfortable sleeping with one arm out, it’s time to leave both arms out of the swaddle.

  • Use a transitional swaddle or sleep sack designed for this stage, such as one with removable sleeves.
  • Keep a consistent bedtime routine to reassure your baby during this adjustment period.

Transitioning from a swaddle to a sleep sack can be challenging if your baby has a strong attachment to the swaddle. Consider using transitional options like the Merlin Sleep Suit or the Zipadee-Zip if they are struggling. Be patient and give them time to adapt.

Step 4: Try a Cold Turkey Approach

Some babies do well with the gradual approach, but others might adapt better when you go cold turkey.

  • Completely switch from a swaddle to a sleep sack in one go.
  • This method works especially well if your baby rolls or if they show signs of rolling. If your child is rolling and safety is at risk, it would be recommended to switch as quickly as possible. 

While this can lead to a couple of sleepless nights, many babies sleep quickly, adapting and adjusting really well. 

Step 5: Create a Comfortable Sleep Environment

Ensure your baby’s sleep environment is conducive to restful sleep:

  • Use a white noise machine to mask external sounds. A white noise machine can help your child connect sleep cycles. Our favorite white noise machines are the Hatch and the Yogasleep Dohm. 
  • Maintain a consistent bedtime routine to signal that it’s time for sleep. A bedtime routine can be simple and truly only a few steps. Consistency over time is key. 
  • Keep the room at a comfortable temperature, as sleep sacks provide warmth but shouldn’t overheat your baby.

If you’re uncertain about making the transition, consulting a sleep consultant can provide valuable guidance tailored to your baby’s needs.

See what this mama had to say about our sleep services below: 

“Prior to working with Danielle, my three month old was sleeping decently, however, there were a few things that I knew could be better. When I began working with Danielle, I knew I wanted my baby to learn how to self soothe so I was no longer rocking her and sleep longer stretches before going back to work as a teacher this coming fall. She put together a personalized plan with every tip and trick I would ever need. Throughout the process, Danielle was absolutely amazing at communicating with me – even texting me back in the wee hours of the morning. She consistently worked with me through any difficulties and always made sure to check in on me.

My little babe was putting herself to sleep by Day 2 and by Day 5 she was putting herself to sleep in under five minutes – saving myself and my husband hours of rocking! Danielle worked with me to get my little one on a schedule which led to more time for mom and dad! I would highly recommend Danielle and trust the Sleep Shore process! Absolutely amazing and wish I would’ve considered this with our first child.” – Mom of 14 Week Old
