Summer wearable blankets for March 2026 baby - help a clueless FTM out!

[Rena001]

Hi everyone,

I’m a FTM (first-time mum) due in March 2026, and I’m currently nesting like crazy! I’m trying to get organized with sleeping bags for the summer months when LO will be around 3-4 months old.

I’ve been looking at 0.5 Tog and 1.0 Tog options, but I’m totally torn on the styles. Are the ones with poppers on both shoulders and a side zip actually easier for those blurry-eyed 3 AM nappy changes? Or is a front zip a better shout? I'm terrified of fumbling with fiddly bits in the dark while a tired baby is screaming!

Also, I'm a bit stumped on the sizing. My midwife says the baby is measuring a bit on the larger side. If I buy the "newborn" or "0-6 months" size, will they grow out of it in a fortnight? On the flip side, I’m panicking about the SIDS risk if the bag is too big – I’ve read that if the neck opening is too wide, they could slide down inside. How do you all find the balance?

Which brands do you swear by for quality and safety? I keep seeing Tommee Tippee (Grobag) and Slumbersac, but are there any "hidden gems" that wash well and stay soft?

Would love to hear your "must-haves" or any "don't bothers"!

Thanks so much!

I don’t remember doing nappy changes in the night at 3-4 months.

we used to get them from Vinted and sell on again when finished. I liked the zip down the side ones at that age but it’s not something worth thinking about now until you know how wriggly the baby is, how they sleep etc.

Swaddling till 2 months worked for us, then I had a few 0-6 and a few bigger ones. In the summer he often slept without anything if it was hot, or a thin cotton sleeping bag.

The midwife mentioned that my LO (little one) is tracking quite large on the growth scans, so I'm expecting a bit of a 'chunky monkey' at birth! I’m keen to get some summer sleeping bags sorted early so they’re all set for the heatwaves.

I’ve seen so many lovely designs online, but I’m a bit of a worrier. If I go for a front-zip style, will it be uncomfortable or 'dig in' when they’re having some tummy time or sleeping on their front? And is the sound of the zip likely to wake them up during a stealthy night change?

On the other hand, are the ones with shoulder poppers a bit of a faff to do up in the dark? Also, total paranoid mum moment here—is there any risk of the poppers coming loose and becoming a choking hazard? I know I’m probably overthinking it, but I just want to be prepared!

I know you want to get organised but really sleeping bags are very easy to buy quickly and you are far better waiting till you actually need them so you know what size and style you are getting on with.

You might not need thin ones till August or at all depending on the summer.

My firstborn loved sleeping bags, second born hated them. See what way your baby is before buying anything that far ahead. 😊

Don’t overthink it. By summer, you literally won’t be doing nappy changes or taking baby in and out of the sleeping bag.

If you are talking about actual summer (June to August, not March), go for 0-6 months and 0.5tog. If it’s cool, you can always dress baby more warmly underneath.

Front zip. You don't want to be wrestling octopus arms in the night. With the front zip, you just unzip from the bottom to access the nappy while the top stays nice and warm zipped up.

I had a March baby. I used newborn 3 tog sleeping bags until about mid May, when a heat wave hit and we went to 1tog. They were especially good in the pram. Often I kept him in them during the day anyway because they're much easier than blankets for cuddling up on the sofa. I also had one in just muslin fabric which was great for the heat waves. They still get a little chilly from drafts even when it's 30°, but really don't need the insulation. Where I am, bags come in every size from 45cm. They're fine with little babies so long as the neck is small enough that there's no way they could slip down into it.

ETA all these people saying they didn't do nappy changes must have got lucky. I'm still doing at least 1 per night at 9 months because mine won't resettle if his nappy is full. It might be more predictable if you bottle feed do they're not taking in fluids over night

As others have said, I would wait and see how big baby is nearer the time to see what size you will need. Or if you are really keen that buy second hand from vinted etc so that if the sizing isn't right you haven't spent a fortune.

I personally preferred size zip ones as found them easier to move out of the way for nappy changes. I think the zip making a sound isn't likely to be an issue- you can do it slowly to be quieter but I never did stealth nappy changes- my babies would never sleep through changes. I never struggled with poppers in the dark, found them quite straight forward. @

In terms of a front zip- there isn't really a necessity to do tummy time with the sleeping bag on, and baby really shouldn't be sleeping on their front until after 1 as it is not a safe sleep position. Some older babies who have learnt to roll will roll onto their front but they should always be placed to sleep on their back.

It's so exciting getting prepared for baby's arrival but I wouldn't think too far ahead as it can be a huge waste of money buying stuff you find you don't need. If baby comes in March you will have loads of time to get sleeping bags before any heat waves.

Some of it depends on the baby..

My first had food allergies and needed changing several a night as she pooed before during and after every feed and fed every 2h. From 3 weeks we coslept every night as she needed to be held all the time. Swaddles and sleeping bags barely used.

My second is much more settled and we were able to stop doing night changes at 2-3 weeks. He has slept a lot more in his crib usually until 3-4 am. We used blankets and swaddles at first and then moved to sleeping bags. We had all of the swaddles donated from a friend. The swaddles were 5-12lb so would cover nearly all newborns. Once they are here you can then figure out what they are like/dislike.

Size isn't always equal. My daughter was 3.11 kg at 38+6 weeks and my son was 3.08 kg at 37+1 weeks but so much smaller than her! We had to drop down to size 0 nappies (2-5lb range) and he was about 5 weeks when he fitted into the clothes she left the hospital in!

I’ve had three children and I don’t think I ever changed a nappy at 3am. It’s an absolute myth that you need to get up, feed, wind and nappy change. We actually coslept so I just put my boob in their mouth and went back to sleep!

I've got a very wriggly 5 week old. Currently we are using side zip ones (bought one and gifted the others) varying from 1.5 to 2.5 tog. If in the 1.5 tog he has a vest and sleepsuit on and just a sleepsuit for the 2.5 tog with the heating around 19-20 celcius in the house. He's very comfortable at that. He's already learning that when the sleeping bag goes on it's bedtime.

It's easy for changing and you can just zip down and work with it under them but if you have a boy think about when they pee in the air and also expect exploding poo nappies at any point. We tend to take little man out of his to feed and change. We always change mid feed as otherwise he goes back to sleep and won't eat enough (he's a very relaxed child!). None of ours have poppers but most of his clothes do and none seem to be coming loose or causing issues so I would try not to worry about that .

There's some great guides regarding layering clothes for different temperatures on the internet and the health visitor will give you advice as well.

I used front zip ones too and can’t remember doing nappy changes in the night at that age.

If you’re worried about how big baby will be, I would wait until they’re here. By the time they arrive the shops will have more choice anyway

Same here. No neex to wind a BF baby. When DD learned to roll she would finish her feed, roll over, burp and go back to sleep

He again @Rena001. I’ve just reread your OP and the best thing I can suggest is reading Babycalming before your LO arrives. It’s evidence based and helps you to find a routine tgat suits both you and your baby. I read it before having DC2 and really wished I’d read it before I had the little intense ball of energy that was DC1

If you’re thinking of BFing I can also suggest some things that might help if you’re interested?

I'd say zip down the front is a bit easier, but don't buy anything yet for when they're 3-4 months. By a month old I was co-sleeping and the cot and all bedding was never used again.

Your baby never did a poo in the night? You struck gold!

What a shame!

What’s a shame OP?

I saw a mum mentioning she’s been co-sleeping with her one-month-old and the cot’s basically just gathering dust now! What a crying shame, especially when you’ve spent a fortune on the nursery. My DH is dead set on getting a proper cot; he’s convinced it’s the only way for the LO (and us!) to get any decent shut-eye.At what age did yours actually start sleeping solo?

Neither went into their own room until 14 months. They have to sleep in the same room as tou anyway till 6 months and by then, i was ci-sleeping and it was easier to just feed and go back to sleep. In fact if you’re BFing you hardly stir at 6 months wheb they wake for a feed.

Both got evicted wheb they stopped wanting to go back to sleep after a feed and instead wanted to practice their new walking skills in the bed.

My advice is either to buy a cheap cot, like the ikea obe or a cot that will morph into a toddler bed so tgat they will get some ise out of it.

Both DNs are very tall though and quickly outgrew their cot.

You don't have to spend a fortune! I'd recommend not spending a fortune on anything as there's no guarantee it will be used. Buy as little as possible in advance and get it when you need it so much can be got next day even second hand.

In our old house we didn't need a baby monitor as we could hear upstairs without one. We moved house when she was 2 and now we couldn't hear her so bought a monitor. As she was older and we just needed to hear her and not see her we could go with a more basic version and for one from Argos next day collection for £15-20 much cheaper than the video ones we might have born for a newborn.

My second is 4 months old and he started rolling last week, on Friday we decided it was probably best to get a play pen for him so he could have a safe place away from the eldest and her small toys. We looked for one on Friday and picked one up for £10 on Saturday morning. It retailed for £40 and looks brand new.

I would also be a bit more flexible in what your baby will like, they haven't read the manual and don't know how you are all meant to get the most sleep! My first was a reflux baby and had to be held for an hour after each feed. She fed every 2-3h! The only way any of us was getting sleep was by cosleeping! My second went in his cot happily and slept but was so so noisy we couldn't sleep!

@Rena001 Co sleeping can be very dangerous. It’s odd that people still do it. I’d get a Moses basket next to your bed in the first place. You will need to be handy. No - didn’t change nappies in the night either regularly. Just odd occasions but mine slept through at 8 weeks - in the cot in their room. We all have different views and I’m not putting a baby in bed with us who could be suffocated.

I'm with @OhDear111 on this, studies show that co-sleeping increases risk of injury and death to babies, especially under 1 years of age. I will take baby into bed with me for cuddles and feed but as soon as he is burped and changed it's back into the moses basket.

We got 2 baskets, one for our room (3rd floor) and one for downstairs. His bedroom has a travel cot that has a changing station on it and eventually turns into a play area. Both moses baskets were free on Marketplace so worth having a look..we just got a new mattress and washed it all down really well.

Have you got some links to say it’s dangerous? I thought as long as you followed the safe bed sharing guidelines it was actually more safe?

Can you link to the studies please? Ive genuinely never heard of them.

How can it be more safe than a baby in a Moses basket next to you? Guidelines? Yes, but they are not always followed. Shock horror - parents drink too much are obese and aren’t aware of what they are doing when they are asleep.
Also why not just tuck baby in with a light covering in the summer? What baby needs a sleeping bag? New invention to get parents to part with money.
