What Are Little Sleepies?
Little Sleepies are baby and toddler pyjamas. With them, they’re made from Lunaluxe® bamboo viscose, which boasts the softness, stretch and breathability bamboo viscose is known for. Not only is this material soft for sensitive skin, but it’s also versatile with a few added perks:

No Scratch Pull-over Design & zipper: Our gowns feature Fold-over Mittens to keep your baby from scratching themselves. Gown Style offers hassle-free Two-Piece to make life easy for Mom and Baby, easy to operate.
How Long Do Little Sleepies Fit Growing Kids
One of the biggest questions I’ve heard from parents about Little Sleepies is regarding fit. After all, kids grow like weeds, and you don’t want to buy new pyjamas only to have them outgrown in a month or two. The good news? Little Sleepies is made with growth in mind.
Stretchy Material for Long Time Use
“I think what makes the bamboo material in Little Sleepies special is that not only is it so soft, it is so stretchy. “And this lets the pajamas grow with your child. And many parents say their kids are able to wear the same pair of Little Sleepies for 6 to 12 months — a major advantage over typical sleepwear brands.
Babies and toddlers particularly love the brand’s popular Zippies (footless zip-up sleepers). These Zippies will fit a larger range and grow with your baby longer. For instance:
- Size 0-3 months can fit up to 6 months.
- Size 6-12 months can fit easily until 18 months.
This stretch comes in handy during those rapid growth spurts!
Generous Sizing Options
Little Sleepies also include plenty of roomy silhouettes, including a two-piece pajama set. These are actually perfect for both toddlers and older kids because they have a baggier fit that allows them to be worn as kids continue to grow, both in height and girth. The waistbands are soft and stretchy; you won’t be pinched.
Cuff Made Up for Extra Length
Another sweet detail: Most Little Sleepies designs come with fold-over sleeves and leg cuffs. These easy roll-up cuffs mean your little ones can grow and they will still fit, making them even more of a sustainable choice.
Parent Tip: Not true to size and advises to order down. Despite how generously sized Little Sleepies are, the extra stretch ensures they won’t be outgrown for months, even if you didn’t order a size up.
Why Size and Fabric Matter
So, how long do Little Sleepies last? The secret lies in what they are made of and their size and versatility.
Bamboo Fabric Longevity
Every Little Sleepies clothing item is made of premium bamboo viscose. This is not only ultra-soft but extremely durable! Bamboo fibres are also resistant to frequent washings, meaning that it’s less likely they will pill or become threadbare after continuous use.
Bamboo’s thermoregulating nature also makes it an ideal all-season choice. Warm in winter and cool in summer, the material regulates the temperature of your child, providing comfort year-round.
A Custome Size That Grows With Baby
Little Sleepies are designed to stretch as your child grows! The genius cuff system lets you roll up and down ankle and wrist cuffs; that way, those outgrown accessories that lengthen the life of an item are no longer a problem. For example:
- Baby and toddler sizes can often fit for 6-12 months (or longer).
- Big kid sizes may last over a year, depending on your child’s growth rate.
Compared to standard pyjamas, which are often quickly outgrown, this growth-friendly design is a major win for parents.
Average Lifespan Based on Age
For Babies (0-12 Months)
Babies grow quickly — most double their birth weight at six months. Despite this, some parents say Little Sleepies have lasted as long as 6 to 12 months for newborns, in part due to how stretchy the fabric is.
This is really helpful, too, in those newborn days when your baby is outgrowing clothes every other week.
For Toddlers (1-3 Years)
Toddlers have a brief let-up in all that growth that starts by being born, but they’re still a blur and on the go. Little Sleepies for toddlers generally last throughout the year, which is saying a lot for active climbers and crawlers.
The cuffing is very, very useful here. Rolling the cuffs up and then down as your child grows allows relatively easy adjustment for extended use.
For Big Kids
For bigger kids, the longevity of Little Sleepies really depends on how quickly your child grows. They last about 16-18 months on average. You may be able to get two years’ worth of wear out of your purchase if your child lands in the middle or low end of the size range.
The bamboo itself has a nice stretch to it, so even if the kids wear them to play and stretch them out, they’re not going to wear out the material.
Additional Tips for Prolonging Their Lifespan
To make the most out of your Little Sleepies, here are some care tips to keep in mind:
- WASH IN COLD WATER: To help prevent shrinking and wearing, please wash your Little Sleepies on a cold, gentle cycle.
- Line Dry or Tumble Dry Low: We recommend not using any heat in the drying process by going to low heat to keep the elasticity of the bamboo fabric.
- Stay away from harsh detergents: Stick to mild, baby-safe detergents to ensure the integrity of the fabric.
- Rotate Between Pairs: If you can accumulate multiple pairs of pyjamas, rotate between them. This will reduce the amount of washing and wear and tear.
Factors That Affect the Lifespan of Little Sleepies
While Little Sleepies are designed to last longer than most children’s pajamas, specific factors can influence just how long you’ll get out of each pair.
Washing and Care
Proper washing and care greatly affect the longevity of Little Sleepies. Because they’re made from bamboo fabric, it’s best to follow these guidelines:
- Machine Wash on Gentle: Always choose cold water to preserve the fabric’s softness and elasticity.
- Lay Flat to Dry: While you can tumble dry on low heat, air drying will help keep the material looking and feeling new for longer.
Following this care advice can help your Little Sleepies withstand frequent wear and continue looking fresh after multiple washes.
Day-to-Day Wear
The Little Sleepies are marketed as sleepwear, but many parents allow kids to wear their sleepers as loungewear or playwear during the daytime (thanks to their softness and cute designs). Though the fabric is tough, a child who hauls themselves around a good deal or who alternately crawls and runs all over during outdoor play might show slightly more liberal signs of wear than normal.
Sibling Hand-Me-Downs
Another reason Little Sleepies are the longest-lasting pajamas is they can be passed down to other siblings. Being gender-neutral and their ability to withstand long-term use also means you will want to reuse them again and again. Many parents say they’ve made it through two or even three Little Sleepies for their kids!
Final Thoughts on Little Sleepies Longevity
Little Sleepies are not only beautiful sleepwear for your baby but an investment in quality, comfort, and practicality for the most special person in your life. With their stretchy fabric, smart design details such as fold-over cuffs and attention to quality materials, these pyjamas are made to endure through growth spurts and beyond.
