These warm pajamas are perfect from babies to big kids.
Cute, Cozy Pajamas To Keep Your Kids Warm When The Weather Cools

From footies to adorable one-piece pajamas, this sleepwear will keep kids toasty.

Originally Published: 

When cold winds start blowing, and the nights get chilly, it’s time to swap out your family’s pajama pieces. Away go the light cottons and linens, in come the soft flannels, warm knits, and cozy footies. But if you open up your kid’s pajama drawer and discover that its contents are now laughably too short, cropped, or tight, some pajama shopping might be in order. You’ll find appropriately close-fitting cotton onesies, adorable flannel two-pieces, and multiple warm-bottom footed options with hand coverings in this collection of cozy kids sleepwear. Each piece can help everyone in your family ward off the winter frost.

Do you have babies at home? As you shop here, just keep in mind that the American Academy of Pediatrics (AAP) advises against putting your little baby to sleep with blankets, so smart layering is the way to go. As per the AAP, babies can sleep with an additional layer of clothing more than an adult needs. Sleeps sacks can be considered for extra warmth, even into the toddler stage. And pajamas should fit close to the body.

Once you have your pajama game sorted, all you and your kiddos need are a few mugs of hot cocoa, fuzzy slippers and you’re set for a comfy-couch kind of night. Cue up Netflix!

Under The Nile Footie

Can you find other adorable footed pajamas for babies? Sure. But this one gets extra nods for the little details that make it special for your babe, and a thoughtful gift to give other newborns in your life (notice the sweet drawstring packaging pouch?). First off, the pajama has side-snaps, which can overlap the fabric in the front for an added layer of warmth. Made of organic Egyptian cotton, this striped design (available from newborn to 6-month sizes) also comes with a warm pea-pod hat; while so cute, it should be worn while baby is awake and supervised, not asleep.


Taylor And Max Velveteen Footie

With soft velveteen piping around the neck and wrists, plus cuffs that double over to keep baby hands warm, this is a dreamy pajama option, not to mention another chic idea to consider for a newborn baby gift. The organic-cotton onesie snaps closed along the inner thighs, so you don’t have to take this piece off entirely when changing your baby’s diaper. Outside of the polyester trimmings, the suit is crafted from organic cotton, which is GOTS certified (that’s the Global Organic Textile Standard, which means, as per the Global Organic Textile Standard website, the fabrications are certified organic within their standards and follow their guidelines for environmental and social treatments).


Owlivia Footed Pajama

The bamboo rayon, organic cotton, and spandex blend is sturdy, substantial, warm, and so completely soft. The fleece in the footie bottoms makes for an even cozier experience. As an added bonus, the sleeves convert into mittens, which can provide even more insulation, and scratchy-nail protection for tiny babes. The adorable cactus pattern, and details like covered zipper and grip bottoms, elevate the piece and take it to luxe territory. Multiple washings won’t compromise the quality. In addition to subtle solid-color versions (think mint green, dark gray, and white), the brands also offers footless varieties in solids and prints for warmer weather.


Miles And Milan Footed Romper With Mittens

Irresistibly cozy and snuggly, this short-sleeve bodysuit comes with a long-sleeve romper and matching hat in fits for newborns and babies up to 12 months old. The trio makes a winning gift thanks to thoughtful details, like snaps along the inner thighs, and a playful smiling-face design on all three pieces. The clothing, made of a soft polyester and cotton fabrication, is washing machine ready. But if you’re shopping for those cold winter months, here’s the best part: The romper comes with sleeves that can be turned into mittens, and optional footie bottoms. So there’s versatility that can work with your baby the whole year through.


Hanna Andersson Long John Pajamas

These popular two-piece sets from the reliable quality brand Hanna Andersson are made of soft organic cotton and fit close to your child’s body for a feeling that’s warm, not suffocating or sweaty. Tight wrist and ankle cuffs add to the warm feel. Why are they so popular? Consider first that the sizes run from newborn all the way up to teenager. Then just have a look at All. The. Prints. From strawberries to lemons to fantastical purple tigers, there are sweet, playful patterns to please everyone in the family. If your kiddo loves dinosaurs, there are versions covered in the magical creatures; and sale prices can bring the pajamas home for under $20.


Nest Designs Sleep Suit

Sometimes keeping things cozy in a safe sleep suit is a surefire way to help your baby sleep soundly through the night. In sizes ranging from 6 months to 6 years, this footless “sleeping bag” is perfectly primed to provide your little one with a warm, restful snooze. Super handy, this cotton-sleeve piece, made with muslin, comes with a 2.5 TOG rating, (which signifies a Thermal Overall Grade); it’s mid-heavy weight, and on super chilly nights you can consider zipping it up with a onesie underneath. For style points, this one features an irresistibly cool geometric print from illustrator Eric Carle.


Free Birdees Toddler Footie

It can be tough to find footies long enough to fit 2 and 3-year-olds, which is one of the reasons why these grip-bottomed onesies from Free Birdees (a company run by mothers) are worth a look. Made of bamboo viscose and 5% Lycra, the supple, stretchy pajama is crafted with a two-way zipper, which any caregiver knows is genius for quick diaper changes while minimizing chills. A sleeveless onesie underneath can provide added protection on cooler nights. When it comes to care, gentle cycles in washers and dryers help keep these pajamas, covered in exclusive prints and patterns, looking and feeling their best.


Hanna Andersson Coverall

It doesn’t matter how freezing cold a winter night gets, some kids just can’t stand to have their feet covered or enclosed while they sleep. Perfect for those little ones, here’s a reliable option from Hanna Andersson, designed in seven sizes for kids up to 3 years old. This warm zip-front sleeper provides the cozy feel of a onesie without the (sweaty) footed bottoms. Considering the comfortably tight fit, tapered wrist and ankle cuffs, and sturdy organic cotton, the adorable green Yoda print becomes a cute bonus. And during one of the brand’s sale seasons, you can score the piece for 20-something dollars.


Mama Owl Chasing Windmills Merino Wool Set

Have you ever wanted to build an outfit around a pair of pajamas? This merino wool two-piece, with timeless blue-stripe print, might tempt your kiddos to do just that. The crew-neck top and long, tapered pants are thin and light. Available in sizes fit to suit 2-year-olds up to 10-year-olds, you can use the set as a layer underneath a one-piece, or a snuggly robe. The long john set has sturdy fabric over the knees, and the merino wool is sourced from New Zealand. Yes, $90 is a splurge, but reviewers on the Mama Owl website explain the joys of the softness that is a Chasing Windmills merino-wool set. If you’re looking for a wintery indulgence, this might be it.


Tiny Jumps Flannel Pajamas

When you think of cozying up on a chilly night in a pair of jammies, you likely think of one word: flannel. Well, this flannel-cotton two-piece, in sizes from 3-to-6-months, up to 6 years old, is designed to feel soft and cuddly. The crew neck has side buttons, the waistline is stretchy, and the pants can be cuffed for a tighter ankle fit. In seven prints featuring fun animals like animated dinos, kitties, bears, and monkeys (plus a pair with buses and trucks), the set can double as kid-friendly daywear — just swap you baby’s slippers for booties, and see if anyone notices.


L.L.Bean Cotton Two-Piece

The outdoorsy brand’s new two-piece now comes in toddler sizes for 2, 3, and 4-year-old kids. The rib-knit cuffs on the wrists and ankles help keep drafts from sneaking up arms and legs for a warmer wear. Made completely of organic cotton, the pieces are fully washer and dryer-proof. The outdoor moose-and-tree print gives it a nature, rather than holiday, vibe, and there are three other print variations, in blush, blue, and beige to consider. To make things even cozier, L.L.Bean makes adorable animal-themed polyester fleece robes for toddlers to wear overtop their pajamas while playing or lounging before bedtime.


Petite Plume Flannel Two Piece Pajamas

Talk about timeless. The gray button-front top and elastic-waist pants are trimmed with a crisp white piping, which makes for a sweet take on cozy flannel. The Petite Plume website offers sizes for infants (starting at 6 months old) and kids up to 14 years old. And while you can toss the cotton pieces in your washing machine, a cold cleanse is recommended (along with a heatless form of drying). For an additional $19.50 (and an additional nine to 12 business days), you could even have the set monogrammed. Just think of what a special gift that could make a child in your life.


Boden USA One-Piece For Kids

Another option for when your toddler grows into a big-kid bed (and likely grows out of the footed-pajama stage), this cozy cotton one-piece can be a cute alternative. With sizes from 3 years old up to 14 years old, the striped pajama is a comfy solution for little kids and pre-teens. Think about buttoning one up over a close-fitting tank top for an extra layer of warmth. The ribbed knit clings close, as do the wrist and ankle cuffs in contrasting hues. Matching pajama movie night, anyone? Think about it, as the Boden brand makes jammies (and even chic, furry, slide-on slippers!) for grown-ups, too.
