What Is A Sleep Sack?

A sleep sack is an all-in-one comfort item, which your baby can relax and sleep inside of. Your cutie pie won’t get tangled up in blankets or sheets and his head remains uncovered when he turns. It’s a wearable blanket for your little one, who can wear it at night while sleeping.

 

Are sleep sacks safe for babies?

Sleep sacks, which fit correctly are one of the safest bedding products available for babies. Your baby has the freedom to move around, yet the neck and the armholes prevent your tot from wriggling out or slipping inside. The best baby sleeping bags reduce the risk of bedding items covering your baby’s face and keep your baby’s temperature at a constant level.

 

How to Choose the Best Sleep Sack

When you’re choosing the best sleep sack for your baby, consider the size, the TOG count, the fabric composition, the clothing, and travel options. Natural sleeping bags fit snuggly at the top to keep your baby from slipping out or inside the sack. Sleeping bags are available in different sizes for different ages such as 0-6 months, 6 to 18 months, and 18 to 36 months. Measure your baby from feet to shoulder.

The TOG rating can confuse most parents. The higher the TOG level, the warmer the baby sack. The lower the TOG level, the cooler the sleeping bag. Check the room temperature to make sure you choose the correct TOG.

Your little one can wear natural fiber sleeveless bodysuits, long sleeved bodysuits or onesies under the sleeping bag. Choose baby sleep sacks with sleeves made of 100% natural cotton or wool bags. Wool keeps your baby at the correct temperature while sleeping, as it’s a natural insulator. Sleeping bags are versatile and parents can use them on the go. Some sleeping sacks accommodate harnesses of a pram or a car seat. You’ll also find sleeping sacks including a 2-way opening zip made for quick and easy nappy changes.
