Best winter bedding options for a three month old baby?

14 replies

Phoenix321 · 27/09/2026 12:03

Just after a bit of advice. Looking for bedding options going into winter for nearly 3 month old. Our house tends to be really hot in summer (around 24-26degrees and even hotter during the heat wave) and really cold in winter (around 16degrees). Baby has never liked to be swaddled. I tried sweetdreamers 0-3month sleeping bags to begin with which she used for a couple of weeks but then I think she got frustrated as to restrictive on her legs which she likes to kick about. So currently using cellular blanket but she moves around in her sleep and kicks them off. Going into the winter months I'm concerned she will get cold so considering trying sleeping bags again but she falls between sizes in the cheaper brands (too small for 6-18 months but 0-6 months will be outgrown part way through winter). Could go back to sweetdreamers which are 3-12months so would last just one winter but also like the look of the Mori clever bags which last 3-24months which would last 2 winters (and look roomier in the legs) but the multi tog one is out of stock everywhere so I'd be looking to buy 2 2.5 tog and the 2 lighter tog ones which is a massive outlay. Also considering merino baby four season bag but again would nearly be £200 for 2 of those so I can have them in rotation if one needs washing (no access to tumble drier and clothes take ages to dry in Winter). The Tommee Tippee multi season ones also look good and much cheaper but the issue is the sizing as 0-6months will be quickly outgrown and concerned they won't be as comfortable and perhaps more restrictive in the leg area. I also risk that she just won't get on with sleeping bags at all! Any advice appreciated.

You are way overthinking this.

Buy some sleeping bags from Asda or another supermarket and if she grows out of them just buy more. They’re cheap and they work.

You should also be aware that blankets at such a young age, including cellular blankets, are not safe for sleep.

We used sleeping bags. No issues and plenty of room to kick their legs.

Covers and blankets are fine as long as the baby is put feet to the foot of the cot/crib and the covers are tucked in under the armpits so they can't go over the face. Sleeping bags didnt always exist so it was sheets and blankets that were used

I agree with the previous poster. There’s no need to have overly expensive sleep bags. We also largely got ours from Asda; they came with a guide telling you exactly what to dress the baby in. Remember, it’s much better to have a cold baby than a hot one!

We also had this one for our little one, it was recommended by Which.

I found these a great alternative to sleeping bags. You can get them easily on vinted much cheaper too

Also if you do try sleeping bags again there’s no difference between the cheap asda and aldi ones and the expensive branded ones ime

No they’re not safe sleep. Babies move about and blankets can get tangled, creating entrapment and suffocation risks.

Just because we used to do something it doesn’t make it safe practice.

The lullaby trust does not warn against them and they are the charity best placed to give SIDS info. This is their info on bedding:

How do I pick baby bedding?
Avoid soft or bulky bedding such as quilts, pillows and duvets. These have been shown to increase the risk of SIDS by three times.
Firmly tuck in sheets and blankets – but make sure they’re not above shoulder height. Sleep your baby in the feet-to-foot position, which means their feet are right at the bottom of the cot so they can’t wriggle down under the blankets
Remember that one blanket doubled over counts as two blankets – This could increase the risk of your baby overheating. If your baby needs an extra blanket, make sure it’s lightweight.
Alternatively, you could use a well-fitted baby sleep bag. Most sleep bag manufacturers recommend products based on the baby’s weight (usually around 4kg or 8.8 pounds) rather than their age. Make sure to check the recommendations before using a sleep bag.
Be sure to remove any soft toys from the cot before each sleep, as these can cover a baby’s mouth.

Types of bedding to avoid:
Weighted swaddles

Weighted blankets
Weighted sleeping bags
Quilts
Pillows
Duvets
Sheepskin.
Soft or bulky bedding is not recommended for babies under 12 months because there is a risk of overheating and their head being covered.

We use the merino wool sleeping bags. Ours are from Merino Kids and Superlove Merino. They’re all from Vinted and all have been great quality secondhand. Merino is temperature regulating so all weather so no need to worry about different tog ratings. The sizing for both (I think) is 3 months to 2 years and my tall 18 month old still just about fits in them so they’re a long term solution. They are expensive even second hand but you don’t need the multiple togs and sizes you need with other sleeping bags and they hold their value really well. If you’re patient on Vinted there are some listed at good prices too. I got one with a tiny hole in it for £15. And as they’re so long, a 3 month old’s legs won’t feel at all restricted.

We had the tommeetippee sleep bags (loads of room for legs to move) from 0-3 then moved to the tommee tippee steppee at 12 months these from next look good though and they do them in 3-6,6-9 etc.

Sleeping bags. If you're worried about the size just get the ones with poppers underneath the arm pit.

Thank you all

We have always used the Pure Earth Collection all season sleeping bag for our now 3yo - she’s literally been in the same once since we bought it at 6 months. Now just invested in one for our son. They really are a quality investment

The sleeping bags with legs and arms are great! Dd2 had a JoJo one and some from Slumbersac.

But if you do splash out on a £200 merino wool one, never put it in a tumble dryer, it will shrink!
