There are several things you should know about safety precautions for your baby.

Although more than one million sleep sacks have been sold, there have been very few incidents involving the safety of the baby. One problem occurs when a baby in a sleep sack ends up in a supine (face down) position. Some babies have suffocated after they rolled onto their stomach while wearing a sleep sack although the problems with sleep sacks have a lower incidence than those experienced with blankets.

The recommendation is to stop using sleep sacks as soon as you notice your baby trying to roll over. The same advice is given for any type of swaddling.

There have been some cases where the zipper of the sleep sack posed a choking hazard and a couple of cases where an opening in the zipper caught a baby’s new tooth, resulting in the extraction of the tooth.

Like with any baby clothing, make sure any design you use doesn’t pose any choking hazards and that all fasteners are securely fastened.

Do not put your baby face down. It greatly increases the risk of injury or death, including SIDS. You should also avoid bumper pads, blankets, soft bedding, and pillows.

Finally, you want to make sure you don’t overheat your baby. Hats can interfere with the ability to cool down in a hot room. If you pay attention and think about what you’re doing as far as keeping your child warm enough but not too warm, you should be fine. Infant’s control of their body temperature isn’t as sophisticated as an adult’s control.


There is no second thought how much a sack can do but it may concern you with its useful life. Many think that sacks are just for baby use but they are wrong. People who love traveling around or for those people whose job is with traveling might face problems with bed allergies. This problem can be overcome by using a sack which makes life and travel easier.

Moreover, babies are quite fragile and to handle them with care sleep sacks are the best choice you can make. These sacks are very handy for parents as they help the baby and the parents sleep deep at night without having the need to look at the child again and again.

So, replace a blanket with a good quality sleep sack to ensure the health of your baby.
