Collection: Baby Sleeping Bags & Swaddles

Tog measures how much warmth the fabric holds in. The higher the number, the warmer the bag. It tells you which room temperature the bag is designed for, so you can choose based on your baby's actual room rather than guessing.

It depends on your room temperature, not the season. Use the 2.5 tog bag for 16-20°C, and the 1.0 tog bag for 20-24°C and above. Every bag comes with a room thermometer and tog guide included, so you can check as you go.

The 1.0 tog bag uses a bamboo and organic cotton blend, chosen for extra breathability in warmer rooms. The 2.5 tog bag is 100% organic cotton, suited to cooler temperatures where you want more warmth held in.

From day one, with the Sweet Dreamers Sleep and Swaddle Bag. It works as a swaddle first, arms in, for the newborn stage. Once your baby starts showing signs of rolling, usually somewhere between 8 weeks and 4 months, you simply unzip the sides for arms out. No need to buy a separate swaddle and sleeping bag.

There's no set age. It comes down to mobility and fit, not a birthday. Once your baby is climbing or trying to walk while wearing it, a sleeping bag can become a trip hazard, and it's time to size up or transition out. Check the sizing on your specific bag as your best guide, since babies outgrow at different rates.

Yes, when sized correctly and fitted properly. They're safer than loose blankets because there's no loose fabric that can cover your baby's face. Ours are also tested to British safety standard BS EN 16781:2018.

No. "Organic cotton" on its own isn't a regulated claim, and plenty of budget and mass-market brands use the term without third-party testing behind it. GOTS certification checks the entire supply chain, from farming through to the finished product. OEKO-TEX tests the finished fabric against a list of over 1,000 substances that could be harmful to health. Sweet Dreamers is certified to both. That's a real difference from an "organic cotton" label with nothing behind it.

Organic cotton is grown without synthetic pesticides, fertilisers or GMOs. But without independent certification, there's no third-party check that a brand's "organic cotton" claim is actually true. GOTS certification verifies the cotton is genuinely organic and ethically manufactured, right through the supply chain. OEKO-TEX tests the finished fabric and confirms it's free from harmful substances.

Yes. Sweet Dreamers sleeping bags are hypoallergenic, made without the harsh chemicals and residues that can trigger reactions in sensitive skin. This is backed by GOTS and OEKO-TEX certification, so it's not just a label claim, the fabric has been independently tested to support it.

Once your baby shows signs of rolling, they need to stop being swaddled with arms in. This is when most parents move to an arms-free sleeping bag.

Machine wash on cold, and either tumble dry on low or line dry. This keeps the fabric soft without breaking down the fibres over time.
