Finding the Best Muslin Sleep Sack

Getting your baby into a sleep routine is one of the most daunting tasks for new parents. You’ll go through ups and downs as your baby wakes up immediately after putting them to sleep, and some of the reasons may be discomfort and feeling cold. For this reason, we think muslin sleep sacks are a great option for anyone that’s looking to create both a safe and warm environment for your baby as they sleep.

We used muslin sleep sacks during our first year with our twin boys and would recommend the SwaddleDesigns Cotton Muslin Sleeping Sack which is available off Amazon for $23.99.

What is a Muslin Sleep Sack?

Muslin sleep sack are made from super soft breathable materials and are made of 100% cotton material. They works by zipping the baby inside, leaving the head and the hands free to move. 

What Ages can use a Muslin Sleep Sack?

A muslin sleep sack is best worn by babies who are transitioning from swaddles which is generally around the 4 month mark. The reason being is that your baby will begin to turn and become more active in their sleep and need something that will firmly stay on them at all times to ensure they keep warm.

In terms of how long your baby can wear a muslin sleep sack for this ultimately depends on your baby with every baby being different. There’s no hard and fast rule here and generally we recommend watching for any signs of overheating or discomfort which may mean your child is beginning to outgrow the muslin sleep sack.
