When to Use a Sleep Sack
Sleep sacks acts as a deterrent from having your toddler learn to climb out of the crib (note I said deter, not prevent). With a sleep sack on, your toddler may very well never make the attempt to scale the crib and never know the freedom waiting on the other side.

Guide to Buying Sleep Sacks
With the plethora of baby products available to parents, I want to take a moment to mention the most important sleep sack features to consider when you purchase your sleep sacks.
Snap vs sewn shoulder strap: snaps make it easy for taking on/off but some toddlers might learn to pull them loose so you may choose to opt for ones that are sewn together.
Under arm snaps: makes the arm hole adjustable for a smaller baby and is used in sleep sacks that will grow with the child.
Zipper direction: zippers that close on the bottom makes it convenient for nighttime diaper changes.
Roomy for the hips: allows your baby’s hips to move freely to reduce the chance of developing Infant Hip Dysplasia.
Zipper placement: on the side vs in middle.
Size: always buy the correct size based upon your baby's weight and length to prevent the chance of baby slipping down inside the sleep sack or the fabric accidentally covering baby’s mouth or nose.
Seat belt slots: eases transfers from car seats and strollers into the crib on nights you know you will miss your child's bedtime.
Material: wool is great temperature regulator but generally takes more laundering care. Cotton is most commonly used and usually easier to wash. Micro-fleece is simple to wash, stain resistant and quick dry.
TOG: choose a TOG that is suitable to the climate and environment your baby is sleeping. There are seasonal vs four-season sleep sacks.
Brand: choose a reputable brand for a peace of mind.
