Comfy for them. Easy for you. The best sleepwear (or all day wear) around for your little ones. Now for the details:

  • Made of the softest, stretchiest bamboo fabric that feels like butter. Bamboo is naturally hypoallergenic, antibacterial and regulates body temperature, making it perfect for year-round wear.  Read more about why we love bamboo here
  • Fold-over hand cuffs up to size 12-18 months. Protect your little ones from scratching themselves without having to worry about those silly mitts that never stay on. 
  • Fold-over foot cuffs on all sizes. Instantly turn the romper into a footie and back again. Cover those little feet when they go to sleep without having to worry about sizing constraints of a traditional footie. 
  • Double zipper. Use the bottom zipper pull for those middle of the night diaper changes and you can easily take out baby’s legs vs having to totally undress them!
  • No snaps, buttons or interior tags. Easy for you, comfy for baby!
  • Extra length. Simply roll up the arms/legs as needed. This, combined with the foot cuffs and extra stretchy fabric allows sizing to be very flexible. Need sizing help? Size chart can be found here. 
  • No chemicals. Do you know most pajamas are treated with harsh chemicals that make them flame-resistant? Ours are designed to fit snugly in accordance with all CPSC regulations. 

  • 95% viscose from bamboo; 5% spandex. Machine wash on cold.

Little Sleepies is proud to donate a portion of each and every sale to Alex's Lemonade Stand Foundation for Childhood Cancer. 

Babies grow SO fast! That's why we designed our sleepwear to be extra flexible in sizing. All of our styles have extra length (easily roll up any extra), foldable foot cuffs (traditional footies are so limiting) and super stretch for longer wear! They are designed to fit snug in accordance with all CPSC guidelines (as they are not treated with any nasty chemicals!). Read more about the breathability and benefits of our fabric here.

The below guides are based on feedback from hundreds of customers.

We recommend sticking to true size/age for the Zippy - there is room to grow and no need to size up.

Softest pajamas!

Love the quality and fit

Color

I LOVE the material and the pjs. They are unbelievably soft, stretchy and the quality is great. However, in the listing for them the background of the print looks gray. So I ordered them for my boy. Upon arrival, the background is clearly a pale purple. The discrepancy is the only reason I’m rating these 4 stars out of 5. Otherwise, I love everything about them, and will continue purchasing from Little Sleepies as these are my favorite pjs for my baby.

Best sleepers ever!

These sleepers are so soft, breathable, functional, and so cute. I love the two way zippers for easy diaper changes. The sleeves and legs can be rolled up with ease for a personalized fit. The material is just awesome, washes well, messes easily come out (trust me, my son had a blow out the first time he wore it), they do not fade or have color transfer. And the prints? So cute, unique, and vibrant!!

Cute, comfy, and functional!

I’m absolutely in love with little sleepies one piece pajamas. The two way zipper and cuffs for both feet and hands are genius. They’re so soft and such high quality, we will definitely be buying them for years to come!
