| Purflo Swaddle-to-Sleep Bag | Best breathable | From £25 |
Sleeping bags replaced loose blankets for good reason: a correctly sized bag can't be kicked off, can't ride over the face, and keeps temperature consistent all night. Fit and tog matter more than brand.
Getting it right
- Tog by room temperature: 2.5 tog for 16–20°C rooms (most UK nurseries most of the year), 1.0–1.5 tog for 20–24°C, 0.5 tog for heatwaves.
- Fit at the neck is the safety point. The bag must not slip over the head — check the brand's weight/height guidance, not just age.
- No hoods, correct armholes, and nothing else in the cot: that's Lullaby Trust safer-sleep guidance.
- BS 8510 is the British safety standard for children's sleep bags — the brands below design to it.
We sell our own GOTS-certified organic sleeping bags, and this guide also covers the best from other brands — the disclosure box above explains how links are funded.
Our picks, in detail
Best all-rounder
1.Tommee Tippee Original Grobag
From £26
The bag that created the UK category. Reliable sizing, every tog rating, endless prints, and washes without losing shape — the default choice for good reason.
Pros
- +Full tog range and sizes newborn to 3 years
- +Robust zips and true-to-size neck fit
- +Widely stocked — easy to buy the next size fast
Cons
- –Standard cotton, not organic, on most prints
- –Popular prints sell out seasonally
Best for newborns
2.Love To Dream Swaddle Up
From £28
The arms-up swaddle that stopped a million startle reflexes. Babies who fight traditional swaddles often settle in this self-soothing position — and the Transition version removes wings for the rolling stage.
Pros
- +Arms-up design lets babies self-soothe hands-to-mouth
- +Twin zip for night nappy changes
- +Transition version eases the move to a sleeping bag
Cons
- –Outgrown quickly — it is a newborn-stage product
- –Sizing runs snug; check the weight chart
Best breathable
3.Purflo Swaddle-to-Sleep Bag
From £25
Purflo’s hypoallergenic, thermo-regulating bag that adapts from swaddle to arms-free sleep bag — a favourite for warm sleepers and eczema-prone skin.
Pros
- +Breathable fabric regulates temperature well
- +Hypoallergenic — good for sensitive skin
- +Swaddle-to-bag design covers the rolling transition
Cons
- –Pricier than the Grobag per bag
- –Fewer tog options than the market leader
How we chose
We build every shortlist the same way: we map the whole UK market for the category, weight the specifications that change daily life (not the ones that look good in adverts), cross-reference sustained buyer feedback across multiple retailers, and sanity-check prices across the retailers we link. Retailers cannot pay to appear, and commission never affects rankings. Prices were verified on the "last reviewed" date and will drift — always confirm on the retailer page.
Your questions, answered
What tog sleeping bag does my baby need?
Match tog to room temperature: 2.5 tog for 16–20°C, 1.0–1.5 tog for 20–24°C, and 0.5 tog above 24°C. Adjust clothing layers underneath rather than switching bags for small changes.
When should a baby stop being swaddled?
Stop swaddling as soon as your baby shows signs of rolling — typically 8–16 weeks. Transition products with removable wings, like the Swaddle Up Transition Bag, make the change gentler.
Are baby sleeping bags safer than blankets?
Yes — a correctly fitted sleeping bag cannot be kicked off or pulled over the face, and keeps temperature consistent. The Lullaby Trust recommends a clear cot: no duvets, pillows or loose bedding under 12 months.
