The BubsNest Verdict

These are soft, affordable basics that make night changes easier with the zip, though some parents report they don't hold up as well after repeated washing compared to pricier brands. Perfect for practical parents who want good-enough quality in bulk without breaking the bank, but skip them if you want heirloom pieces or your baby is between sizes since M&S sizing can be inconsistent.

⚠️The sizing runs all over the place depending on the specific design, so buy multiple sizes if ordering online or you'll likely need to exchange.

BubsNest expert analysis of 5 parenting forum discussions

“Praised for quality cotton fabric and versatile sizing, but some fit struggles for bigger babies”

7.8

Solid Choice

These pure cotton sleepsuits from M&S are a solid choice for newborns and young infants. Parents highlight the soft, breathable fabric and appreciate the range of sizes from 5lbs to 3 years. Many find the zip-front design convenient for dressing. However, some report the suits run small, especially as babies grow, and note the fabric may not stretch enough to accommodate larger or older babies comfortably. Overall, these are seen as a great value option for the early months, but may need to be swapped out sooner than expected for some families.

What parents love

Soft, breathable cottonParents praise the high-quality, pure cotton material as soft, comfortable, and breathable for newborns.
Versatile sizingThe wide size range from 5lbs to 3 years allows these sleepsuits to grow with the baby for several months.
Convenient zip-frontThe zip-up front makes for easy dressing and undressing, especially with wriggly infants.

Worth knowing

Sizing runs smallSome parents report the suits fit snugly, especially as babies get bigger, and may need to size up sooner than expected.
Fabric lacks stretchThe non-stretchy cotton material can feel restrictive on larger or older babies, limiting mobility.
May not last longDue to the sizing and fabric limitations, these sleepsuits may need to be replaced more quickly than other options.

Best for

  • Newborns and young infants under 1 year
  • Parents looking for a budget-friendly, quality cotton option

May not suit

  • Larger or older babies who need more room to move
  • Families looking for sleepsuits to last through the toddler years

Tips from parents

Before You Buy

Consider sizing up, especially if your baby is on the taller or heavier side, to ensure a comfortable fit as they grow.

Getting the Most Out of It

Wash these sleepsuits in cool water and air dry to help maintain the soft, stretchy feel of the cotton.

Safety Note

Always supervise babies in these sleepsuits, as the zip-up front could potentially pose a strangulation risk if left unattended.
