Features to Consider in a Sleep Sack for Toddlers


Most toddler wearable blankets are made from cotton because it is soft and highly breathable. Australian merino wool is also great as the material is silky-soft and hypoallergenic.

There are other materials you would choose like fleece, just make sure the material is soft, safe, washable and hypoallergenic.

Breathable Fabric

The best sleep sack for babies should have the ability to feel warm in winter and cool in summer to be comfortable in all seasons. Great example of breathable materials is cotton and Australian merino wool.

A breathable fabric keeps the baby comfortable all round the year to give you a peaceful mind and a great sleep as well.

Shoulder Snaps and Inverted Zipper

These features play the same role in easing the diaper process and dressing. The inverted zipper opens from bottom to top for easy changing.

Some toddler sleep sacks are made with a plastic zipper, however, if you’re looking for durability, make sure the zipper is made from metal because it’s lifelong.

The zipper should be covered with a linen both on the inside and top to shield your angel from occasional scratches that would hurt the gentle skin.

Generous Fit

You are looking for a toddler wearable blanket. So, who said the wearable blanket for toddlers should be tight? A generous fit is the best because it allows the legs to move at night to prevent hip dysplasia. Your little one will also feel more comfortable when they sleep than on a tight sleepsack.

Also, a roomy sleepsack grows with your baby and you won’t have to invest in another one until they transition out of the sleeping bags

Under Arm Snaps

The snaps allow for custom fit as you can adjust the sleep bag to fit a newborn or a toddler. This way, you won’t have to invest in lots of sleep bags as you can customize the wearer to fit the growing child.

Frequently Asked Questions

Which is the best toddler sleep sack? Well, there are tons of brands in the market, therefore what may be best to you may not be good to another user. However, popular brands include Halo, Baby Deedee, Nested bean, Woolino, 1 st laugh and more. Be sure you select the right sleeping sack that suit the weather around.

Are baby sleeping sacks safe? Yes, they are. Actually, they’re the safest form of beddings for infants and toddlers. Unlike the lose blankets, they do not tangle the baby at night reducing the SIDS risk.

How long can a toddler use a sleep sack? Many parents prefer using a sleeping sack as long as the baby is comfortable. Toddlers can throw the blankets at night but a sleep sack will remain intact all night. Unless your baby is uncomfortable with the wearable blanket, you may continue to use it until he/she is 3 to 4 years.

What should the baby wear under the sleep sack? This will depend on the climate. However, we recommend the baby to wear a pant or another form of clothing especially on winter. Babies also catch cold a lot easily so this may vary from one baby to the other irrespective of the climate.

Can a baby feel excessively hot in a sleeping sack? The best way is to monitor your baby by touching. If they feel too warm and sweating profusely, you may need to adjust the clothing. American Academy of Pediatrics recommends keeping the sleeping room at regulated temperature to reduce SIDS risks. Also, the baby should not wear more than one extra clothing that we’re wearing to feel comfortable.
