Newborn Sleep
Newborn sleep is unpredictable, but the gear around it does not have to be. We test swaddles and sleep sacks through real nights and translate the TOG and safety jargon into plain language.
Topics
Swaddles
A snug wrap helps a newborn sleep longer. How to do it, and which blankets hold up.
Sleep Sacks
When swaddling ends, sleep sacks take over. TOG, sizing, and the sacks worth buying.
Bassinets and Cribs
Bassinets, bedside sleepers, and the convertible cribs that go from newborn to toddler.

The best swaddle blankets for newborn sleep
A good swaddle is large enough to wrap snugly and breathable enough to stay safe. Muslin does both, and softens with every wash. We tested these through real newborn nights.
The best sleep sacks for babies
A sleep sack is a wearable blanket: warmth with nothing loose in the crib. The two things that matter are TOG, which is how warm it is, and the fit at the neck and arms. We tested these through real nights.

Newborn Sleep: frequently asked questions
- What is the safest way for a newborn to sleep?
- Alone, on their back, in a crib or bassinet with a firm flat mattress, no blankets, pillows, or bumpers. Same room as you for the first six months.
- When will my newborn sleep through the night?
- Sleeping a long stretch of five or more hours usually starts somewhere between three and six months. Newborns wake every two to four hours to feed; that is normal.
- Should I swaddle?
- A swaddle helps many newborns sleep longer. Stop swaddling the moment your baby shows any sign of rolling.
