When the baby sleeps better, you sleep better too. However, that’s unlikely with loose blankets that are known to twist and interfere with your baby’s breathing!

The best sleep sack for newborns and infants will work the magic as these products are tested to keep your bundle of joy snug, comfy and safe every day and night of every season and climate.

We have baby sleeping sacks that are designed for every age and stage, but if you have a newborn or infant, then this resourceful guide will be very handy.

But with so many sleep sacks on the market, how do you know the best baby sleep sack? Read on.

Comfort

Sleep sacks are made to be womb-like and imitates the same environment as a mom’s wombs. Because a sleeping sack is an alternative to swaddles blankets, it keeps the baby warm while allowing for free hip and leg movements.

However, the baby sleeping blanket may be uncomfortable as your baby grows as the swaddle blanket may be too restrictive for the active baby.

Safety

Swaddle blankets are made to replace loose blankets and stuffed animals that are unsafe to newborns and infants. Also, they reduce suffocation risk as they do not allow newborns to turn back at night and impede their breathing.

Sleep sacks do not immobilize the baby’s hips and arms and therefore do not interfere with their development to negate the potential of Hip Dysplasia.

How to Swaddle a Baby with Sleepsack

How to Choose the Best Baby Sleep Sack

There are lots of sleep sacks and knowing what features to look when shopping can be overwhelming. The following are important features that characterize the best sleep sacks for babies in market stores.

Breathable fabric

Natural or organic cotton is the most breathable when compared to other constructions. Cotton is also hypoallergenic and will not cause irritation to the sensitive skin. For summer climates, cotton does not heat up.

However, you may opt for polar fleece like Baby Deedee Fleece Sleeping Bag or flannel as this material is typically warm for winter climates.  Unfortunately, do not go for fleece if the baby is less than six months after birth. Avoid any other synthetic material as it may not go well with your baby’s skin.

Strong Zippers with Liners

Some sleeping sacks are made with metallic zippers, while others are plastic. A sturdy zipper is made from metals and should not stuck at some sections. The zipper should run from top to bottom for easy diaper changing late at night.

The fabric lining or protector on the zipper is vital because it acts as a barrier to shield the zipper from scratching the skin to cause irritation.

Snapped Shoulder Straps

Snapped shoulder straps makes putting on and off a lot easier so there no need to remove the whole sack when changing the diaper.

As the baby grows, the adjustable shoulder snaps are adjusted to make the baby sleeping sack roomy for the growing baby.

The best baby sleep bag should contain Velcro closure to contain your baby’s hands; and multiple ways to adjust the wearer to adapt the baby’s style of sleep for a seamless transition into sleepsuits.

Size

Because babies are of different size and age, choosing the right size for your baby will be very crucial. A too small sleep sack is uncomfortable and may pose development problems.

Again, a too big sleep sack may prompt the baby to escape from the swaddle aside from posing an SIDS risk like the loose blankets.

Look at the dimensions or the sleep sack sizing chart to confirm the right size for your angel.
