A baby sleeping bag keeps your baby warm all night, without blankets that slip off with the slightest movement. We’ve rounded up options for every need: for cold winter nights, for babies who still sleep in a cot, for newborns, for very cold homes, and for warmer seasons.

✨ To stay warm without uncovering in winter

On cold nights, babies kick off their blankets and often wake up cold. A winter sleep suit with legs stays on no matter how much they move and lets them get up and walk around the house.

The Tender Elephants is a 2.5 tog sleepsuit with detachable sleeves that you can remove when the weather gets milder, and it fastens with a zip. Customers note that it washes best inside out on a low spin cycle. If you don’t need detachable sleeves, the Tender Classic is also a 2.5 tog sleepsuit with legs, at a more affordable price.

✨ To keep feet from getting caught in the cot bars

While your baby sleeps in the cot and isn’t walking yet, a sleeping bag without legs keeps their feet inside the fabric. Buyers say this stopped their baby from pushing their feet through the cot bars.

The Grobag SleepBag is a winter 2.5 tog sleeping bag with no sleeves and a zip fastening. Buyers say it is also suitable for the tumble dryer.

✨ For a newborn who wakes up from their own arm movements

During the first few months, a baby’s arms can jerk in their sleep and often wake them up. A swaddle-style sleep sack keeps them tucked close to the body.

The Love to Dream Swaddle Up is a 2.5 tog sleep sack for winter, with a zipper. Buyers describe it as a solution for babies who move their arms and wake up. If the room is warmer, the Meyco Swaddle is a 1 tog blanket that fastens with Velcro; buyers note that it does not have a leg zipper for diaper changes.

✨ For homes that get very cold at night

Where indoor temperatures drop significantly overnight, a higher-tog sleeping bag keeps your baby warm without extra blankets.

The Owli Sleeping Sack is a 2.7 tog sleepsuit with legs and a zipper fastening. Buyers in cold regions say their baby stays warm and that the sleeves keep their arms warm too.

✨ For cool autumn and spring nights

During the transitional seasons, a winter sleeping bag feels too heavy, but the nights are still cool. A 1 tog sleeping bag is ideal for this time of year.

Tender Marble is a 1 tog sleeping bag with detachable sleeves: keep them on for cooler nights and remove them when it gets warmer. It fastens with a zipper.

✨ For warm summer nights

In summer, especially with the air conditioning on, a lightweight sleeping bag keeps your baby covered without weighing them down.

The Tender Marble 0.5 tog is a summer sleeping bag with a 0.5 tog rating, sleeveless and with a zipper.

To choose a tog rating, consider the room temperature, not just the season, and follow the manufacturer’s instructions on what your baby should wear underneath.
