The recommended choice for infants while they are sleeping.
A Sleep sack or sleep bag is also known as an infant/toddler wearable blanket. It’s like a sleeping bag for your baby that they are unable to get out of.
A sleep sack/sleep bag is like a blanket and will keep your child’s temperature regulated while keeping their sleep space safe. Health Canada recommends nothing in the crib with your baby, just a tight fitted sheet until they’re 12+ months.
Typically, when you use a sleep bag for every sleep, it becomes a positive sleep association. It can become a “lovey” to them when they’re too young to have a lovey in the crib with them and makes sleeping outside of their home much easier when traveling!
