À propos de ce produit
A baby who runs warm needs sleepwear that breathes all night, not just at bedtime.
Alligators on swings, elephants, kites, hopscotch — playground math.
Forbes named these the best baby pajamas in 2025. The sleeper is the workhorse of the under-layer — soft against the skin, quick to change in the dark, and built to survive the laundry a newborn puts it through.
Material. TENCEL™ Lyocell with a touch of spandex for stretch. TENCEL™ is the wood-pulp fiber Lenzing spins in a closed-loop process that recycles 99% of its water and solvents, certified to OEKO-TEX Standard 100.
The print. Cream ground with alligators on swings and seesaws, small elephants and pink bunnies, kites being flown by our Wolfie, hopscotch grids, balloons, small numbers, clouds, and trees.
Construction. Fold-over cuffs cover the hands for the first few months — no mittens to lose — then fold back when the baby wants them free. A two-way zipper runs chin to ankle and opens from the bottom for diaper changes, the neckline is tagless, and the shoulder and crotch seams are reinforced where a sleeper gets pulled on and off twice a day.
Sleepers and sleep bags work together. The sleeper is the layer underneath — it isn't meant to provide the warmth on its own. Pair with a 1.0 TOG TENCEL™ Sleep Bag for a 21–24°C nursery, a 0.5 TOG muslin sleep bag for 24–27°C, or wear alone in a warm room above 24°C if the baby protests the sleep bag.
Why TENCEL™ for a sleeper. A sleeper is worn most nights and washed two or three times a week, so we match the fiber to the job: TENCEL™ Lyocell keeps its softness and shape through heavy laundering. Our muslin pieces answer a different brief — swaddles, crib sheets, and 0.5 TOG bags use Tanboocel® Bamboo Viscose for breathability in the heat.
Sizing. 0–3M, 3–6M, 6–9M, 9–12M, 12–18M, 18–24M. Size to current measurement. A sleeper that's too long bunches at the hands and ankles and rides up overnight.
Care. Machine wash cold and tumble dry low. Don't bleach, and don't iron the printed areas. Wash it Tuesday, wash it Friday, wash it forever — TENCEL™ holds its surface through the routine.
Safety & certification. Tested to Health Canada's Children's Sleepwear Regulations (SOR/2016-169), and to CPSIA and ASTM standards. The material is certified to OEKO-TEX Standard 100, and Loulou Lollipop is a Certified B Corporation.
Common questions
Are TENCEL™ pajamas better than generic bamboo pajamas?
For longevity, yes. TENCEL™ keeps its surface through repeated, heavy laundering. TENCEL™ Lyocell keeps its face through wash after wash — and no nursery item is washed more than pajamas. The pajamas your baby still has at 18 months are TENCEL™.
What temperature should baby's pajamas be?
Pajamas are the under-layer, not the sleep system. Match weight to the room: long-sleeve TENCEL™ under a 1.0 TOG bag for 21–24°C nurseries, short-sleeve under 0.5 TOG for 24–27°C, sleeper under 2.5 TOG for 16–20°C. The bag handles the warmth for you.
Why fold-over cuffs?
No one warns you how fast newborn fingernails grow — or how quickly they end up at the cheeks. Fold-over cuffs cover the hands without mittens that fall off. Somewhere around 4–6 months, the cuffs flip back for good; the hands have jobs now.

Nos normes de sécurité
- The fabric is so nice and has a good quality
- After 2 washes its still pretty good condition no piling compared to other brand
- This fabric is made for eczema prone babies
The cut of this onesie is horrible! The neck opening is so wide that it looks like she is wearing an off the shoulder top. Whoever came up with this design needs to redo this design entirely and choose a fabric that will hold its shape. I ordered two of these onesies and now regret wasting my money on them. I had high hopes this would work out since it is a Canadian company and it is not cheap but sadly I would not recommend!
Thank you for taking the time to bring this to our attention and our sincerest apologies that the fit was not what you expected. We are always here to help & happy to help when issues are encountered. Our Customer Care team has been in touch via email for more insight and to assist further.
I am disappointed with the quality of the darker colour items and how they have degraded after only a few washes. The “stargazing bear” blue colour already looks faded and pilly after less than 5 washes. After contacting customer service, I was told this is normal for this fabric. Given the price point of these items, I would expect much better longevity.
I was excited about this sleeper! the material felt beautiful and the quality seemed great. After just two washes and hang‑drying, it’s already pilling everywhere , which is really disappointing because I love supporting Canadian brands.
We love the waffle knit material of this sleeper and the smooth zipper. Unfortunately, the colour faded exponentially after the first wash while following tag instructions. We were very disappointed with this as the vibrant colour was what we initially liked about it so much.
Initially, I really liked this pajama;it felt soft and cozy on my baby, and fit really well, also, the zipper is very nice. However, we have only had this pajama for 1.5 months and already, the knees are worn through because my baby is crawling. We have many sleepers from other brands that have not worn through at the knees. Unfortunately, I cannot recommend the sleeper and am very disappointed with the quality.
Love supporting Canadian but unfortunately this fabric didn’t wash as well as I had hoped, especially for the full price I paid. Size fits bigger than most and the neck seemed to stretch out.
Comfy but didn’t last. Colour washed away quickly, an had a hole in the waffle fabric after a month.
Amazing quality, best BB clothes we've purchased even my husband notices the quality. I bought a quilts, muslin blanket swaddles, multiple sleepers, hat, teether, multiple clothes. I'm obsessed!
Bought the waffle sleeper last week for my 10 month old. After 1 wash (cold water & hung to dry) the fabric had pilling and this fabric is partially thin as the knee already has a hole from my son crawling. I have only ever put my children in Loulou sleepers as they are always great and always stand up to growing babies/toddlers. Just disappointed in this particular fabric.
Absolutely loved how soft this waffle sleeper was and love the flip over feet but after one wash (as per instructions) the colour has faded and it looks worn out.
I ordered smoke blue sleeper, at that time the picture as showing it opens from the back but it doesn’t open from the back
I tried to buy a bigger sizes for my LO so he can wear in the winter and the year after but the sizing is way off! My 17lb 50th percentile weight 6 month baby is apparently too big for this sleeper in size 12-18m. Great fabric but I guess he’ll have to wear the 18-24m I was saving for next year and cut out the cuffs as they'll be too long.
I really love the prints and materials used but the hand cuffs are soo variable making some of them crazy hard to put on. I have one 6-12 month that has nice sized cuffs while another has much smaller cuffs. Sadly I have a 12-18 month one that has cuffs that are even smaller the smaller 6-12 month... This seems like perhaps a manufacturing/quality control issue...? If you are considering buying a sleeper I would suggest going somewhere where you can buy in person to see the size of the wrist cuffs. Also as a side note, not sure why an older child would need fold over hand cuffs??
I had to switch to footless sleepers for my 7 month old because he’s long and lean and he keeps getting one or both of his feet caught in the body of footed sleepers in the middle of the night. Anyway, these sleepers are amazing for long, lean babies. I bought a waffle one and a regular one. The fit is perfect for him with some room to grow, and the best part is that the ankles and wrists stay where they should. The only reason I’m giving 4 stars is because after the first wash the grey mudcloth sleeper started to come apart at the seam on the ankle and I’m a little disappointed that the stitching isn’t better quality for the price.
I bought this baby sleeper hoping for great quality similar to all my purchased in the past, but it tore after just a few uses. I'm disappointed
Super soft, we love the fold over mitts and socks! Couldn’t be more in love with the pattern as well.
I found the colour of this sleeper to be far lighter than I was expecting. I was also really disappointed because within a few wears/washes the stitches came undone on the cuff. I contacted loulou lollipop's customer service and didn't receive a response.
Really tight! Purchased 2 of these in 18-24 and they are different sizes unfortunately. One is really small and tight and the other fits great
I am so sad. I want to support local so badly and the prints are all super cute! But my baby is a little chubby boy with arm and leg rolls. The arm and legs sleeves are just too tight :( Please!!! Please!!! Please!!! Make these inclusive for all babies! Again, I want to support local so badly!! I put I’d recommend to a friend, but only to a friend who’s baby is not chunky!
