Swaddle blankets and sleep sacks are two significant items for newborns. Not only newborns but also support aged 24 to 36 months toddler! The sleep sack is a great alternative to swaddle blankets


A loose swaddle blanket is riskier for newborns after two/three months. Then they try to roll over. It’s better not to use a swaddle when your baby tries to roll over. A sleep sack helps really well that time. No threats are remaining with it. Even it reduces the risk of SIDS.

What is the Best Time to Use Muslin Sleep Sack?

You can start using a sleep sack on your baby from day one! But it’s better to wait for a few days. Since there is a chance of sleeping injury or accidental moments, we should not take any risk. Swaddle blanket is fine at that time.

Many parents start using this after 3 or 4 months. However, we recommend starting from 3 months or before when your baby shows signs of rolling over. It is completely fine for the infant. You can use it for 24 months or sometimes even more! As long as your baby feels comfortable with the item. 

Pro Tips

  • Put the sleep sack after the baby completes its meal. Do not feed after putting the suit. 
  • Your infant can use a muslin sleep sack up to 3 years of age. In fact, it is as long as you want to hear “Mommy, fix my blanket”. 
  • Use mild detergent for hand washing. Dry naturally under the sun.

Your baby can wear footie pajamas based on the thickness of the sleep sack. Check the sleeping bag TOG rating. Make sure the sleeping bag is not too tight with footie pajamas. 

Do Babies Need Onesie Under Sleep Sack? 

Whether your baby should wear a onesie or footie under the sleep sack, depends on the TOG rating of the sleep bag. If you have 1.0 TOG and are colder than 69°F, adding one layer of extra clothing is okay. But not more than that because muslin itself is perfect for regulating body temperature. 

Is Wearing Only Diaper Under Sleep Sack Good for Baby? 

It is okay to wear only a diaper if your baby sweats a lot. Or else, wearing a cotton short-sleeve t-shirt, or a onesie makes it perfect. Muslin fabric is breathable and lightweight. So, you do not need to worry about overheating.
