Match it to the Smiley Sharks sleep pieces and the whole crib reads as one design.
Smiling sharks and little fish — the friendly version of the shark phase.
A crib sheet has to do three things well: tuck tight and stay tucked, dry fast enough that a two-sheet rotation actually works, and look good enough to earn its place on the registry page. This one is built for all three.
Material. Tanboocel® Bamboo Viscose, blended with cotton and woven into open-weave muslin. Tanboocel® is a branded bamboo viscose made through a closed-loop process — third-party verified, with a lower water and chemical footprint than the generic bamboo rayon most brands quietly label "bamboo." It gets softer after the fifth wash than on day one, the opposite of how cotton ages.
Fit. Sized to US standard cribs (28 x 132 cm / 52 in, up to 23 cm / 9 in of mattress depth). Elastic runs the full perimeter — corner-only elastic is how a sheet pops off at 2 a.m. and ends up bunched under the baby's leg. The deeper pocket also fits the thicker memory-foam mattresses most parents are buying now.
The print. Cream-ivory ground (navy binding) with watercolour smiling sharks — great white, whale, hammerhead, and tiger — in white, grey, and blue tones, with small fish and blue stars.
Care. Machine wash cold and tumble dry low. Tanboocel® takes the dryer better than bamboo rayon, with less pilling and shrinkage over time. Don't bleach; iron on low only if you need to.
How many you need. Two is the minimum, three is the answer: one on the crib, one in the wash, one to absorb a sick night without a midnight dryer run. The open weave dries in about two hours on low, so the rotation actually works.
Adjacent products. Pair with a matching muslin swaddle for the newborn months or a 0.5 TOG muslin sleep bag in the same print for a coordinated registry set. The Newborn Gift Bundle collects the coordinating pieces in one box.
Safety & certification. Tested to Health Canada's Textile Flammability Regulations, 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
What size crib sheet fits a US standard crib?
US standard cribs are 28x132 cm / 52 in with a mattress up to 15 cm / 6 in thick. These sheets are cut to fit that footprint with enough depth (up to 23 cm / 9 in) to wrap securely. The elastic runs the full perimeter, so the corners don't pop off at 2 a.m.
How often should I wash a crib sheet?
Weekly is the baseline. After any spit-up, diaper leak, or sick night, sooner. Tanboocel® Bamboo Viscose dries in about two hours on a low dryer setting, which is why a two-sheet rotation usually holds.
Are muslin crib sheets safe?
Yes — with one rule. The fitted sheet has to fit the mattress tightly with no excess fabric the baby could pull up. These sheets are sized to US standard cribs specifically, and the elastic is engineered to hold under repeated washing.

- Softest sheets! This is our third, and we can't be happier.
- Love these sheets. Sooooo soft I'm actually jealous, very very cute prints.
- They get softer with each wash, have the cutest design and fit our crib mattress perfectly.
I’m very disappointed with this product. I have used the sheets for less than a week and it is already pilling a lot! Their clothes and teethers are such good quality. I don’t know why their sheets are so terrible.
Our little one is picky & I'm so glad we gave these sheets a try! They are super soft, the cutest prints & seem like awesome quality. She sleeps so much better & has even slept through the night on occasion, but she usually wakes once. She's 3 months old :)
These go great in our nursery! Already washed and dried once and they held up great with no shrinkage. (Washed on cold and dried on low).
Really wanted to love the crib sheet since the print was so cute and the fabric so soft! However it was slit open after one wash in a “delicate†cycle when we tried to put it on... don't know what to do with it now. I will still recommend all other muslin products (blankets, swaddles) but not the crib sheet.
Love my new Sushi fitted crib sheet!! My friends gave me so many compliments for it too. It's muslin so it's super soft as well. Can't wait for my baby to use them ^^
It’s sooo soft
The purchase wasn’t for me but my sister seems happy with it obviously isn’t using it but I’m sure it will be good as it is Canadian product and it arrived promptly at my parents house.
Very happy with quality and fit of the crib sheets
Loosens up on crib mattress and threads are beginning to fray already
Loosens up on crib mattress and threads are beginning to fray already, its been a month.
pattern is lovely and they feel nice, but I bought 2 and both have quite significant pilling after just a couple washes
These crib sheets are the best. I have a sheet and blanket set for my babe at daycare as well as sets at home.
Very silky and soft. Very thin. Can catch easily on velcro by accident.
Fit well on a standard crib. Soft and breathable. They can stretch out quick and get little puckers but it goes away once washed and replaced.
So soft and such a cute print. Will be getting more in different colours
Love the quality and design
Holy wow these sheets are SO soft. Color is vibrant, elastic is strong. Would recommend!

Softest sheets! This is our third, and we can’t be happier. This size ended up fitting our crib mattress a bit looser than our others which was nice! A little less effort to get it around the corners.
My baby has very sensitive eczema skin and this fabric is gentle, smooth and so soft! I need to change the covers every 1-2 days so it's a plus that it is big and stretchy with the elastics to make changing the mattress quick and easy.
