What TOG Sleeping Bag Does a UK Baby Need?
The TOG your baby needs depends on the temperature of the room they sleep in. Use this UK guide:
- 0.5 TOG: bedroom above 24°C, the warmest summer nights in most UK homes.
- 1.0 TOG: bedroom 20 to 24°C, typical of spring and autumn. Boori's 0-6 month sleeping bag is 1 TOG.
- 2.5 TOG: bedroom 16 to 20°C, the nursery temperature The Lullaby Trust recommends and typical of UK winter.
Use a nursery thermometer, as UK bedrooms vary a lot between a well-insulated new-build and an older terraced house. Check your baby's chest or the back of their neck: it should feel warm, not hot or sweaty.
Never add a loose blanket on top of a sleeping bag for a baby under 12 months. Adjust warmth with the layers underneath instead.
Why Choose Muslins for Everyday Care?
Muslins are worth having because one light cotton cloth covers feeding, winding, changing and shade, and it washes and dries fast.
Light cloths are easy to wash and quick to dry, and kids muslins work for swaddling, burping, and shade on the pram. You can also use them as a light top sheet during warm months when the room feels cosy.
Use a muslin as a top sheet only for children over 12 months. Never cover a pram hood fully with a muslin, as it can trap heat inside.
Muslins feel soft on the skin and fold up small for the nappy bag, and kids muslin bedding helps you keep spares ready without filling the cupboard.
When Should I Stop Swaddling My Baby?
Stop swaddling at around 4 months, or as soon as your baby shows signs of rolling, whichever comes first. A swaddled baby who rolls onto their front cannot push back onto their back, which raises the risk of SIDS.
If you swaddle a newborn, The Lullaby Trust advises:
- Swaddle no higher than the shoulders.
- Keep it firm but not tight, with hips free to bend.
- Use a single thin layer, such as a cotton muslin.
- Always place a swaddled baby on their back to sleep.
When you stop swaddling, move to a fitted sleeping bag in the right TOG and the correct size for your baby.
How Do I Build a Simple Layering Kit?
Build a simple layering kit with two or three breathable cloths, a sleeping bag in the right TOG and a spare of each.
Start with two or three breathable cloths and one warm cover, and add a spare so the bed can be remade at night without fuss. Many families use a light throw over a fitted sheet, then add or remove layers as the seasons change.
You can match the sizes of your cot set by browsing Cot & Cot Bed Fitted Sheets, which keep corners snug and tidy.
For babies under 12 months, the warm cover should be a sleeping bag, not a throw or blanket.
When Can a Baby Use a Blanket at Night?
Loose blankets and coverlets are not suitable for babies under 12 months. The Lullaby Trust advises a fitted sleeping bag in the right TOG instead. From 12 months, a lightweight blanket or coverlet is suitable, which is why Boori coverlets are labelled from 12 months.
Pick a soft cover that folds back easily and washes well; a single layer is often enough in a warm room. For cooler homes, a second layer can be placed on top and removed quickly at the first feed.
A warm cover that dries fast helps you reset the bed before the next nap, and a kids blanket should feel gentle when touched against the cheek.
Why Use a Sleeping Bag Instead of a Blanket?
A sleeping bag is safer than a blanket for babies because it cannot be kicked off or pulled over the face, and it keeps your baby at a steady temperature all night.
A zip-up bag can help busy sleepers stay covered without loose sheets in the cot, and the arm shape you choose depends on the stage your child is in. You can use light weights in warm rooms and add a layer on top when the weather turns.
A simple, well-sized kids sleeping bag makes bedtime steady because it fits the body and keeps feet cosy during long sleeps.
The "layer on top" should always be clothing under the bag, not a blanket over it, for babies under 12 months.
What To Look For In Each Piece?
Pick soft, breathable fabric that is easy to wash and quick to dry. Check the size, seams, and zippers so each piece fits well and feels gentle against the skin.
- Muslins: Choose soft weave and smooth hems so they feel gentle on skin, and wash before first use for extra softness with kids muslins.
- Blankets: Pick easy-care fibres that dry quickly and fold flat, and keep a spare for late changes with a kids blanket.
- Sleeping Bags: A baby sleeping bag is quite different from a sleeping bag kids would use. It is not only much smaller, but also more specific to the baby's size and the season. When selecting a baby sleeping bag, make sure that the size and the tog are suitable.
What Size Sleeping Bag Does My Baby Need?
Boori baby sleeping bags come in 0-6 months and 6-18 months sizes. Choose the size that fits now, as a bag that is too big can let your baby slip down inside or let the neck slide over their face.
Choose newborn and baby sizes for the early months and step up as your child grows taller. Check the length from shoulder to feet for a bag and the width of the cot for a throw, so layers sit flat.
A good fit stops bunching at the sides and helps sheets and covers stay in place, and you can order every size online from Boori. We have a selection of Kids' Muslins, quilt cover sets and mattress protectors on the website.
How Do I Care for Muslins, Blankets and Sleeping Bags?
Care for muslins, blankets and sleeping bags by following the care label, washing with a mild detergent and drying each piece fully before use.
Follow the care instructions on the tag to keep the fabric soft. Keep a small basket near the change table for fresh cloths and a second basket for laundry, so routines are clear.
You can keep sets grouped in labelled boxes from Nursery Storage, so night swaps take seconds and mornings start tidy.
What Does a Complete Cot Sleep Setup Need?
A complete cot sleep setup needs a firm mattress, a waterproof protector, a fitted sheet and a sleeping bag in the right TOG. Start with one of our cot and cot bed mattresses, add a waterproof layer from our mattress protectors, then finish with a fitted sheet.
For the full range in one place, browse our mattresses and bedding collection. When your child moves to a bed after 12 months, our quilt cover sets take over from the sleeping bag.
Are Weighted Blankets Safe for Babies and Children?
Weighted blankets are not suitable for babies or children under 2 years. For children aged 2 and over, check NHS and The Lullaby Trust guidance before use. Boori's range has lightweight, breathable blankets suitable from 12 months.
Families often ask about heavy bedding and how to keep children cosy when the weather is cold. We focus on light layers that you can easily add or remove, and our sets do not include a weighted blanket for kids because we keep sleep simple and breathable.
If your home gets very cool at night, you can add a warm layer that still feels soft to touch, and a kids fleece blanket can help when mornings feel crisp.
What Are the Safe Sleep Rules for Baby Bedding?
The safe sleep rules for baby bedding are simple: back to sleep, feet to the foot of the cot, a clear cot and no loose bedding under 12 months.
Keep covers below the shoulders and tuck them in firmly at the sides of the cot. Use sleeping bags that fit well, ensuring the neckline and armholes are positioned correctly. Follow your local safe sleep guidelines and keep the bed clear of extra items.
In the UK, that guidance comes from The Lullaby Trust. Keep the room at 16 to 20°C, and never use hats, pillows or bumpers in the cot.
What Everyday Tips Help Bedtime Run Smoothly?
Small habits make nights calm and simple. Use these tips to keep changes quick and sleep cosy.
- Two-Set Rule: Keep one set on the bed and one set clean and dry, and rotate them after each wash for reliable kids muslins.
- Quick-Swap Bundle: Store a spare blanket and bag together in a basket so you can remake the bed quickly if there is a spill during the night.
- Travel Pack: Roll one cloth, one cover, and one bag in a tote for visits and naps away from home, so the sleep feels familiar.
- Season Switch: Move lighter cloths to the front of the drawer in spring and warmer throws to the front in autumn so the right piece is easy to find.
How Do I Set Up the Whole Nursery?
Set up the whole nursery by keeping large furniture neutral, leaving a clear path to the cot and placing a dimmable lamp for night feeds.
Match your bedding colours to your furniture for a calm look, and keep large pieces neutral so small accents can change with the seasons. If you are planning a full refresh, consider Nursery Furniture Sets to keep the room coordinated.
Keep a clear path from the door to the cot, and place a soft lamp where you can dim it for feeds; this helps babies settle with gentle light.
How Does Boori Deliver Baby Bedding?
Boori delivers baby bedding free to mainland UK with no minimum spend. Smaller items such as muslins and sleeping bags are sent by Royal Mail and usually arrive faster than furniture.
Orders typically process within 1 to 3 business days before dispatch, and delivery usually takes 7 to 10 business days after the item leaves the warehouse. Therefore, it is best to check the delivery timeframes and expectations for your specific address. Boori does not offer in-house furniture assembly, and the team can recommend trusted third-party assemblers if you want help on the day.
If you ever need guidance on parts or care, you can reach the weekday team for help. The team can help with any question about your bedding plan.
