Arms-Up Cotton Baby Sleep Sack

The material and zip are good quality but the 3-6 months size came up noticeably large on our daughter who is a smaller build. We've had to wait for her to grow into it rather than use it straight away. Would still consider buying again but would size down.

Lovely and soft against the skin and does help with the startle reflex, but it takes longer to dry than our other sleepwear after washing. Not a huge issue since we have two, just something to be aware of if you only buy one.

Our son needed about a week to get properly used to having his arms up rather than down by his sides, so the first few nights were a bit fussy. Once he adjusted it worked really well though. Good product overall.

Really happy with how it works and the fabric quality, only wish there were a couple more pattern options to choose from. Everything else about it has been spot on for our daughter's sleep. Would still recommend it.

The quality is lovely and our baby sleeps much better in it, but the 0-3 months size felt snug on our son by about 11 weeks. Had to size up earlier than expected. Still a good buy overall, just check the length guide carefully.

Not one for writing reviews usually but this has made such a difference to our evenings that I wanted to say so. The arms up shape means our son doesn't fight it like he did a normal swaddle. Thoroughly recommend.

A lot of baby products feel a bit cheap but the zip on this one is proper quality and hasn't snagged once in two months of daily use. Our daughter seems comfortable in it and settles quickly at nap time.

We were both dreading the newborn stage of broken sleep again with our second, but this has honestly made the nights easier. The stitching and zip feel sturdy, not flimsy like some we looked at. Good value overall.

Ordered the 0-3 months for my newborn and the sizing was spot on. The zip pull at the top is covered so it never touches her chin. Would happily buy this brand of sleep sack again for any future children.

No complicated folding or wrapping technique needed, you just pop baby in and zip up, which is all you want at bedtime when you're exhausted. The fabric is thick enough for a cooler room but not too warm either.

My son is quite a mover in his sleep and this has stopped him accidentally waking himself up with his arms the way a loose blanket used to. Fits true to size for his age. Really happy with this purchase.

Liked it so much after the first one that I ended up ordering all three colourways so we always have a clean one ready. The cream with gold hearts is my favourite but they're all nicely made.

The cotton is noticeably softer than the swaddle we were using before, and it hasn't bobbled after several washes. My little boy seems properly relaxed in it rather than fighting against it like he used to.

Wasn't sure about spending this much on a sleep sack but it has honestly saved our evenings. No more fighting with a blanket that comes undone halfway through the night. The zip runs smoothly every single time.

Unlike a tight swaddle wrap, there's plenty of room around the legs and hips for natural movement, while the top stays snug. Our health visitor actually commented on how well fitted it was. Would recommend to any new parent.

Took this travelling with us last month since it packs down small and washes easily in a hotel sink if needed. Baby slept just as well away from home as he does in his own cot. Really glad we brought it.

Our newborn was waking herself up constantly until we tried this. Within about three nights she was sleeping in much longer stretches. The size guide was accurate too, the small fits her perfectly at 9 weeks.

Used a similar style with our first and went straight back for this one with our second. The zip guard at the top means it never catches under the chin, which happened with a cheaper one we tried. Highly practical design.

Compared to a couple of swaddle blankets we tried first, this is far easier to use and the baby can't wriggle out of it. The combed cotton feels really gentle against the skin. Ordered the golden cream and it still looks new after weeks of use.

Being able to unzip from the bottom for a nappy change without taking his arms out is honestly such a small thing but makes such a difference at 3am. Fits our 4 month old well in the 3-6 month size. Really pleased with it.

Was sceptical about the arms up design at first but my little one has always liked her hands near her face anyway, so it made sense. No more being woken by her own arm movements. The fabric feels proper quality too.

Got this for my sister's new baby and she messaged me the next day to say he'd slept four hours straight for the first time. The pink heart design is gorgeous in person too, better than the photos online.

Bought two of these for my daughter and they've been through the wash more times than I can count, still just as soft. The stitching has held up perfectly too. Would definitely buy again for a second baby.

The two way zip is such a clever idea, you can change a nappy without unzipping the whole thing and letting all the warmth out. Our son stays half asleep through the change now. Ordered the blue one and the stars print is really sweet.

My little one used to wake herself up every couple of hours with her arms flailing about, but since we started using this she's settling so much better. The arms up cut really does seem to stop the startle reflex waking her. Bought the 0-3 months in the cream heart print and it's lovely and soft.
