Organic Swaddles, Sleep Sacks & Sleepers
Babies spend about 12–16 hours a day in their sleepwear. These breathable cotton swaddles, wearable blankets, transition sacks, and zip sleepers help keep the sleep space safe without loose blankets or synthetic fleece.

Breathable Cotton Sleep Sacks
Loose blankets in the crib · $30–$50
A wearable blanket keeps your baby warm without anything loose in the crib, and it zips easily for middle-of-the-night diaper changes.

Swaddle Transition Sleep Sacks

Once your baby starts rolling, swaddling has to stop. Arms-out and convertible transition sacks make the change easier. The HALO and Woolino picks are unweighted; the two Nested Bean Zen picks are gently weighted (see the safety note).

FAQs
When should I stop swaddling my baby?
The AAP recommends stopping swaddling as soon as your baby shows signs of trying to roll over, often around 2–4 months. Switch to an arms-free sleep sack or a transition sack at that point.
Are weighted sleep sacks safe?
The American Academy of Pediatrics (AAP) advises against weighted sleep products for infants. Its parent guide says: "Don't use weighted blankets, sleepers, swaddles or other weighted objects on or near your baby." The CPSC gives the same advice. If you are considering a gently weighted product, such as the Nested Bean Zen sleep sacks and swaddles shown above, check with your pediatrician first.
What TOG sleep sack should I use?
As a general guide, use a lightweight 0.5 TOG sack in warm rooms (about 75°F and up), a 1.0 TOG sack around 69–74°F, and a heavier 2.5 TOG sack in cooler rooms. Dress your baby in one light layer underneath, and check the back of their neck for sweating.
