    OEKO-TEX STANDARD 100 certifies that every component of a textile item has been lab-tested and found free of harmful substances above set limits.

    What it checks

    • Testing of yarn, fabric, buttons, and other accessories against a list of over 1,000 regulated substances
    • Stricter chemical limits for products with more intensive skin contact, including a dedicated infant/toddler product class
    • Compliance with chemical regulations such as REACH, CPSIA, and the ECHA-SVHC candidate list
    • Annual review of substance limit values and one-year validity per certificate

    What it does not cover It tests for chemical residues only and does not certify general product safety features like choking hazards, flammability, or mechanical construction.

    This certification is held by the brand or manufacturer, not by Birch. We show it because the brand states it for this product. Summarised from the certifying body's own page.

    • FSC Certified

    Certified by Forest Stewardship Council

    FSC certification traces wood and paper-based materials in a product back through the supply chain to forests managed under FSC's standards.

    What it checks

    • Forest management practices checked against FSC standards (100%, Recycled, or Mix sourcing labels)
    • Auditing of certificate holders and monitoring of forest management organizations
    • Traceability tools such as blockchain-based tracking of certified material

    What it does not cover This label addresses forest sourcing and traceability of wood/paper materials; it does not test or certify the safety, chemical content, or performance of a finished product.

    This certification is held by the brand or manufacturer, not by Birch. We show it because the brand states it for this product. Summarised from the certifying body's own page.

    • Assesses a company's impact across areas like climate action, human rights, and governance
    • Based on a self-assessment (B Impact tool) that is independently audited and verified by a third party
    • Follows a framework aligned with ISO 17021-1 requirements for certification bodies
    • Applies to the whole company, not to specific product lines or items

Weighted across 10 criteria

CURATEIQ

TrustScore breakdown

91 /100

We take what's most important for a product to determine the TrustScore. Here's our research:

Sleepwear Flammability Compliance 92

It uses the snug-fit route rather than chemical flame-retardant treatment for its sleepwear, and confirms testing to 16 CFR 1615/1616 along with CPSIA and ASTM standards, though the exact label wording isn't quoted.

Fiber Content & Origin 91

The exact fiber blend is published for this sleeper — 94% TENCEL Lyocell, 6% spandex — along with detail on the closed-loop, solvent-recovering manufacturing process for the TENCEL fiber, though no organic certification applies to this particular blend.

Textile Certification 92

OEKO-TEX Standard 100 is named for the sleeper fabric on the brand's page and separately repeated by a retailer carrying this material in its own listing.

Recall History 92

We queried the complete CPSC recall registry (1973–2026) directly. One hit surfaced from 2022: a flammability-standards violation recall covering a different one-piece pajama line sold in 19 named prints, not this Sleeper. No other filings against this brand exist in the registry. The recall is CPSC #22-165, announced in June 2022.

Certification Credibility 92

The fabric is named as OEKO-TEX Standard 100 certified on the brand's own page, and that same claim is independently repeated by a retailer carrying the product in its own listing.

Chemical Finish Avoidance 91

Loulou Lollipop states that no wrinkle-resistant, easy-care, water- or stain-repellent, antimicrobial or flame-retardant finish is applied to the sleeper, whose fabric is stated to be OEKO-TEX Standard 100 certified.

Construction & Fastener Safety 84

The sleeper has reinforced shoulder and crotch seams and a two-way YKK zipper for diaper changes. Recent reviews praise the zipper's quality, though a few find its pull large enough to rub against the baby or scrape the floor while crawling.

Dye Safety 92

Dye chemistry on this printed fabric falls under the same OEKO-TEX Standard 100 certification for its sleeper fabric, which screens for harmful substances including restricted dyes.

Transparency & Support 85

A 3-month defect warranty is published, but the garment's country of manufacture is not stated even though the company's Canadian headquarters address is.

Hardware & Print Safety 91

The sleeper's two-way zipper is a YKK zipper stated to be nickel- and lead-free, and the sleeper's prints are made by digital or reactive dye printing with AZO-free dyes on fabric stated to be OEKO-TEX Standard 100 certified.

A closer look

FAQs

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 70–75°F nurseries, short-sleeve under 0.5 TOG for 75–81°F, sleeper under 2.5 TOG for 61–68°F. The bag handles the warmth for you.

Why fold-over cuffs?

Newborn nails grow faster than any trimming schedule, and the face is the first thing they find. Fold-over cuffs cover the hands without mittens that fall off. By 4–6 months the hands want out — fold the cuffs back and let them work.

Customer Stories

Sentiment Summary

Reviewers consistently describe the fabric as very soft and stretchy, and a few say it suits babies with sensitive skin.
Many reviewers single out the fold-over hand and foot cuffs, which let the sleeper be worn longer as a baby grows.
Some reviewers report pilling, fading or lint after only one or two washes, even when following the care instructions.
A few reviewers find the zipper pull large, saying it rubs against the baby or scrapes the floor while crawling.
Most reviewers find the sleeper true to size or roomy enough to grow into, while a couple still find the wrist cuffs snug.
Many reviewers feel the sleeper is worth the price for its softness and build, though a few were disappointed in how it held up for the cost.

Absolutely best material, cutest print, and I love the hand/foot covers
Lam_Power
I’m a huge fan of your quality products and love purchasing them for my grandson! Patterns are especially cute and the fabric is so soft on his skin!
BdeB
We have bought several of these sleepers amongst other Loulou Lollipop items. High quality, very soft, great fit with optional fold-over cuffs, cute patterns, they wear well, and they don’t shrink in the wash. Loulou Lollipop is a go-to brand for us.
KristenAO
I like these sleepers for the 2 way zipper, the snugger fits but the fabric quality is really disappointing. I’m not sure if it’s the blend of fabrics but even after washing in delicate cycle, cold water in a laundry bag and hanging to dry- the fabric is not as soft anymore and is pilling. This is after 2 washes. Compared to my all cotton onesies from other brands that are less than half the price of these - I will not be repurchasing more of these sleepers.
SSS5991
I love the design and the breathable fabric but, the onesie has lint on it after just one wash even though I followed the washing instructions.
