Baby Sleep Sacks: Essentials for Every Stage of Sleep
Choosing the right baby sleep sacks shouldn't take a science degree. Our collection covers every TOG weight and size, from the newborn swaddle transition through the toddler years, so you can find a safe, cozy wearable blanket without guessing. Every sleep bag follows AAP safe sleep guidance, skipping the loose blankets and bumpers that come with the territory of a traditional crib set-up.
Each piece is cut from soft, breathable fabric with a roomy, hip-friendly shape that lets your baby move naturally without restricting their hips or legs. A dual zipper with a zipper garage makes 3 a.m. diaper changes fast and fuss-free, and every piece holds its softness and shape wash after wash.
Whether you're outfitting a nursery, replacing a blanket your toddler keeps kicking off, or building a baby shower gift, this lineup of baby sleep sacks has a fit for every stage.
Sizing Baby Sleep Sacks From Newborn to Toddler
Sizing runs from XS for the smallest newborns up through XL for bigger toddlers, so the same trusted baby sleep sacks can carry your kiddo from their first weeks home through the move to a big kid bed. Start with an infant sleep sack for the earliest weeks, then move into our toddler sleep sacks range once your little one is cruising and needs their feet free in a sleep bag walker style.
Wearable Blankets Built for Safer Sleep
A wearable blanket takes the guesswork out of bedtime layering, since there's no loose fabric to kick off or get tangled in overnight. Our bamboo sleep bag styles come in three TOG weights, a lightweight 0.5 TOG for warm rooms and summer nights, a 1.0 TOG for standard nursery temperatures, and a plush 2.5 TOG for the coldest months, so there's a wearable blanket suited to whatever the thermostat says.

Frequently Asked Questions
Have questions? We've gathered the most common ones in this section to help you quickly find the answers you need.
Pick a 0.5 TOG for room temperatures above 75°F, a 1.0 TOG for the 69 to 74°F range most nurseries sit in, and a 2.5 TOG for rooms below 68°F. When in doubt, dress your baby in one extra light layer underneath rather than sizing up the TOG on your bamboo sleep bag.
Most babies move from an infant sleep sack into our toddler sleep sacks once they outgrow the infant range, typically starting around 18 months, though it depends on your child's height and weight. Check the height and weight ranges on the size chart for each product page and choose the size that matches your toddler's current measurements, since we don't recommend sizing up on sleep bags given our fit guidelines are set for safe sleep.
A wearable blanket has no loose fabric that can ride up over a baby's face or get tangled around them overnight, which is why the AAP recommends sleep sacks over loose blankets for infant sleep. The enclosed, fitted design keeps your baby covered without the hazards of a traditional blanket.
A sleep bag works well until your toddler starts standing and cruising around the crib, at which point a sleep bag walker gives them the same cozy warmth with feet free for safe mobility. Most families switch to the walker style once their toddler is pulling up to stand.
Check the height and weight range on each product page, since our baby sleep bag sizing runs from XS for small newborns up to XL for bigger toddlers. If your child falls between two sizes, choose the size that matches their current height and weight rather than sizing up, since a proper fit is important for safe sleep.
Yes. Every bamboo sleep bag is machine washable at low temperatures, so spit-up, blowouts, and everyday messes wash out easily without losing softness or shape.
Customers say this fabric is especially gentle on babies with sensitive or eczema-prone skin, thanks to its smooth, breathable feel. It's not intended to treat or cure any skin condition, but many families with sensitive-skinned little ones keep reaching for it.
Yes, baby sleep sacks are safe for both naps and overnight sleep and are recommended by the AAP as a safer alternative to loose blankets in the crib. Choose the TOG weight that matches your room temperature for a baby sleep bag that works for either daytime naps or nighttime rest.
Once your newborn shows signs of rolling, usually around 8 weeks, it's time to stop swaddling and move to arms-free baby sleep sacks. Our Sleep Bag Swaddler is designed specifically for that transition, with a removable wrap that converts an infant sleep sack into a stand-alone sleep bag.
