Newton Baby Mini Crib Fitted Sheets (2-Pack) | Organic Muslin Cotton, Ultra Breathable & Soft, Machine Washable, Fits Any Mini Sized Crib 24" x 38" (Sage) Review (2026)

What you get

This is a 2-pack of fitted mini crib sheets from Newton Baby, made from organic muslin cotton in a soft sage green. Each sheet is cut for a mini crib mattress measuring 24 by 38 inches, the standard size used by most mini cribs, playards with a mini crib insert, and bassinet-to-crib conversions. Newton Baby sells this same muslin sheet fabric across its full crib sheet lineup, from mini sizes up to standard cribs, so the material and construction match what the brand uses on its larger sheets. The sage colorway is a plain solid rather than a print, which makes it easy to pair with wood or white mini crib frames without clashing with a patterned mattress or bumper. Buying a 2-pack means a spare sheet is always on hand for middle-of-the-night changes.

Material and breathability

The sheets are made from organic muslin cotton and Newton Baby's crib sheet fabric is Global Organic Textile Standard certified according to the brand's own product page, which covers organic fiber content and restricts harmful chemical processing. Muslin is a loosely woven, lightweight cotton fabric, and that open weave is what makes it more breathable than tighter knit jersey sheets. For a mini crib used in a warm nursery, a guest room, or during summer travel, that extra airflow can help keep a sleeping baby cooler than a thicker cotton or microfiber sheet would. The tradeoff the site's own cons list flags is real: a light, thin weave like muslin shows spit-up and formula stains more readily than a darker, denser jersey knit, so expect to notice marks sooner even after washing.

Fit and sizing

Newton Baby lists this sheet as fitting any mini sized crib at 24 by 38 inches, and the brand's own mini sheet product page describes all-around elastic for a snug fit on mattresses up to a few inches thick. That elastic hem is what keeps a fitted sheet from popping off the corners when a baby is rolling around, which matters more on a mini mattress than a standard one since there is less surface area for the fabric to grip. Before buying, it is worth double-checking your own mini crib or playard mattress dimensions, since mini crib is a general category and pad thickness can vary a little between brands, even though 24 by 38 inches covers the vast majority of mini and portable crib mattresses on the market.

Care and durability

Both the retailer listing and Newton Baby's own site describe the sheets as machine washable and pre-shrunk, which means normal laundering should not noticeably change the fit over time the way an untreated cotton sheet sometimes does. Muslin is a fairly light fabric, so it also tends to dry faster than a heavier jersey or flannel sheet, which is useful when you only have two sheets in rotation and need one back in the crib quickly after a wash. Newton Baby's direct site also advertises a trial period for its bedding when purchased straight from the brand, though that policy is tied to buying from newtonbaby.com rather than a marketplace listing, so it is not something to assume applies automatically here.

Who should buy it

This 2-pack suits parents furnishing a mini crib, playard, or bassinet-to-crib setup who want an organic cotton option and do not mind paying more than a basic jersey 2-pack costs. The sage solid color is a safe, neutral choice if you want the sheet to blend into a natural wood or all-white nursery rather than stand out with a print. If your main concern is hiding stains between washes, a darker jersey knit sheet will likely do a better job day to day, and if budget is the priority, plain cotton jersey sheets are typically cheaper for the same 2-pack count. But for breathability in a warm room and organic material, this is a solid, straightforward choice.
