From 9 months, U.S. rules say pajamas must be snug-fitting or flame resistant, so look for Carter's Snug-Fit cotton or its flame-resistant fleece. ## Key takeaways - Up to 9 months, sleepers can be roomy; from 9 months, CPSC rules require pajamas to fit snugly or be flame resistant. - Snug-fit cotton pajamas carry a yellow hang tag that says to wear them snug-fitting. - For warmth, add a sleep sack over a cotton sleeper rather than loose blankets; the AAP says nothing loose belongs in the crib. ## Products (chosen from listings, not tested) 1. **Simple Joys by Carter's Baby 2-Way Zip Cotton Footed Sleep and Play** (details: https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07Y2JW91D) — The everyday cotton sleeper to buy several of. - Pros: Two-way zipper from neck to toe for quick diaper changes; Cotton footed one-piece sold by Amazon; Multiple colours and prints - Cons: Sleep and play sizes; check the size chart for older babies 2. **Gerber Baby 2-Pack 2-Way Zip Thermal Footed Sleep 'N Play** (details: https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B0DR3CK6ZP) — A cotton thermal two-pack for cooler nurseries in the first months. - Pros: Mini waffle thermal knit with stretch, per Gerber; Two-way zipper and a neckline protector to keep the pull off the chin; Two in a pack, sized newborn through 9 months - Cons: Stops at 9 months 3. **Burt's Bees Baby Organic Cotton Sleep and Play Footed Pajamas** (details: https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B0DPNF21P8) — Buy it if organic cotton matters to you, for the first nine months. - Pros: GOTS-certified organic cotton; Diagonal zip with a chin guard; fold-over mittens on newborn and 0-3M sizes; Non-slip grips on the feet for early movers - Cons: Relaxed, roomy fit, sized up to 9 months 4. **Kyte Baby Dual Zipper Footie in Bamboo Rayon** (details: https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B08283BLB8) — The soft splurge for babies who run warm. - Pros: 97% bamboo rayon, 3% spandex: very stretchy, per Kyte; Dual zipper neck to ankle; Fold-over cuffs on newborn and 0-3M sizes; sole grips from 6-12M - Cons: About twice the price of the cotton two-packs; Thin fabric; pair it with a sleep sack in a cold room 5. **Simple Joys by Carter's Snug-Fit Footed Cotton Pajamas, 3-Pack** (details: https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07GKVNH2V) — The cotton option once your baby is out of 9-month sizes. - Pros: Snug-fitting cotton, which U.S. rules allow for sizes over 9 months; Full-length zipper with a chin tab; tagless; Three pairs, sold by Amazon - Cons: Must fit snugly; don't size up for room to grow 6. **Simple Joys by Carter's Flame Resistant Fleece Footed Pajamas, 3-Pack** (details: https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07CKZTX2B) — The warm fleece pick for cold nights after 9 months. - Pros: Flame-resistant fleece, so it can be loose-fitting; Zipper from collar to ankle with a chin tab; elastic cuffs; Three pairs, sold by Amazon - Cons: Polyester fleece is warm; watch for overheating in a heated room The best baby pajamas are the boring ones: a cotton footed sleeper with a zipper that opens from the bottom, bought in packs. The [Simple Joys by Carter's 2-way zip sleeper](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07Y2JW91D) and the [Gerber thermal two-pack](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B0DR3CK6ZP) cover the first nine months for little money. After 9 months the rules change, and you want pajamas labelled snug-fitting or flame resistant, like Carter's [Snug-Fit cotton](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07GKVNH2V) or its [flame-resistant fleece](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07CKZTX2B). We compared these on their Amazon listings, checked through Amazon's product API on publication day; we haven't tested them. Safety notes come from the CPSC and the American Academy of Pediatrics. ## How we chose We kept footed pajamas and sleep-and-play sleepers sold by Amazon or the brand, from makers with a long run of baby sleepwear on Amazon. Then we picked for the jobs parents actually have: cheap everyday cotton, a little extra warmth, organic cotton, a soft stretchy splurge, and two options that meet the sleepwear rules for sizes over 9 months. We left out anything with loose hoods, ties or attached blankets, and magnetic closures, which we'd rather not explain to a teething baby. ## The six sleepers ### 1. Simple Joys by Carter's 2-Way Zip Cotton: best everyday value Carter's Amazon line is the default for a reason: plain cotton footed one-pieces with a zipper that runs neck to toe and opens from either end. Unzip from the feet for a 3 a.m. diaper change and your baby's chest stays covered. Buy three or four; leaks and spit-up mean most newborns need more than one a night. **Buy it if** you want the cheapest cotton sleeper that does the job. **Skip it if** you want organic cotton. ### 2. Gerber 2-Way Zip Thermal Sleep 'N Play: best for a cool room Gerber's thermal two-pack is a mini waffle knit with some stretch, a two-way zipper, and a neckline protector that keeps the zipper pull off the chin. It's a little warmer than plain cotton without being fleece. It's sized newborn through 9 months. **Buy it if** your nursery runs cool. **Skip it if** your baby is already in 12-month sizes. ### 3. Burt's Bees Baby Organic Cotton: best organic GOTS-certified organic cotton, a diagonal zipper with a chin guard, fold-over mittens on newborn and 0-3 month sizes, and non-slip grips on the feet. Burt's Bees calls the fit relaxed and roomy and sizes it up to 9 months. **Buy it if** organic cotton matters to you. **Skip it if** your baby is past 9 months. ### 4. Kyte Baby Dual Zipper Footie: best soft splurge Kyte's footie is 97% bamboo rayon and 3% spandex, so it's very stretchy and soft, with a dual zipper from neck to ankle and fold-over cuffs on the smallest sizes. It costs about twice what the cotton two-packs cost per sleeper. The fabric is thin, so in a cold room pair it with a sleep sack. **Buy it if** your baby runs warm or has sensitive skin. **Skip it if** you're buying in bulk. ### 5. Simple Joys by Carter's Snug-Fit Cotton 3-Pack: best cotton after 9 months From 9-month sizes up, U.S. sleepwear rules require pajamas to be flame resistant or snug-fitting. This three-pack is the snug-fitting cotton route: close to the body, full-length zipper with a chin tab, no tags. Snug means snug, so buy your baby's actual size, not the next one up. **Buy it if** you want cotton pajamas for a toddler. **Skip it if** you like a loose fit. ### 6. Simple Joys by Carter's Flame Resistant Fleece 3-Pack: best warm pick after 9 months The other route under the rules: flame-resistant fleece, which can be cut loose. These have a collar-to-ankle zipper, a chin tab and elastic cuffs. Fleece is warm, so in a heated room a cotton snug-fit pair plus a sleep sack may be more comfortable. **Buy it if** your house is cold at night. **Skip it if** your baby sweats in fleece. ## All six compared | Sleeper | Fabric | Fit | Closure | Sizes | Sold by | Amazon price | |---|---|---|---|---|---|---| | [Simple Joys 2-way zip cotton](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07Y2JW91D) | Cotton | Regular | Two-way zip | Baby sizes | Amazon.com | see the current Amazon price on the page | | [Gerber thermal 2-pack](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B0DR3CK6ZP) | Cotton waffle thermal | Regular | Two-way zip | NB–9M | Amazon.com | see the current Amazon price on the page | | [Burt's Bees Baby organic](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B0DPNF21P8) | Organic cotton | Relaxed | Diagonal zip | Up to 9M | Amazon.com | see the current Amazon price on the page | | [Kyte Baby footie](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B08283BLB8) | Bamboo rayon + spandex | Stretchy | Dual zip | Baby and toddler | Kyte Baby | see the current Amazon price on the page | | [Simple Joys Snug-Fit 3-pack](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07GKVNH2V) | Cotton | Snug-fit | Full zip | Over 9M | Amazon.com | see the current Amazon price on the page | | [Simple Joys FR fleece 3-pack](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07CKZTX2B) | Flame-resistant fleece | Loose | Full zip | Over 9M | Amazon.com | see the current Amazon price on the page | ## The 9-month rule The CPSC's [children's sleepwear rules](https://www.cpsc.gov/FAQ/Childrens-Sleepwear) cover pajamas in sizes larger than 9 months up to size 14. In those sizes, sleepwear must either pass a flame-resistance test or be tight-fitting. Snug-fitting cotton pajamas carry a yellow hang tag and a label telling you to wear them snug because they're not flame resistant. Garments sized 9 months and under are outside the sleepwear rule, which is why newborn sleepers can be roomy cotton. In practice: up to 9 months, any of these is fine. From 12-month sizes, buy pajamas labelled snug-fitting or flame resistant, and don't put a toddler to bed in a loose cotton T-shirt and sweatpants. ## Dressing for the room, not the season The AAP's safe sleep advice is to keep soft objects and loose bedding out of the crib and to avoid overheating. Warmth comes from layers your baby wears: - **Warm room:** a cotton sleeper alone. - **Cool room:** a cotton or thermal sleeper plus a sleep sack. Our [sleep sacks by TOG guide](https://nurseryproof.com/sleep-nursery/best-sleep-sacks-by-tog) matches the TOG rating to room temperature. - **Cold room:** a fleece sleeper or a cotton sleeper under a warmer sleep sack. Feel the back of your baby's neck or chest; sweaty means too warm. Hats are for outdoors, not for sleep. For the rest of the crib, see our [safe sleep guide](https://nurseryproof.com/sleep-nursery/safe-sleep-guide-whats-safe-in-a-crib) and [crib sheets and mattress protectors](https://nurseryproof.com/sleep-nursery/crib-sheets-and-mattress-protectors). ## Sizing and washing - Baby sizes run by weight and length more than age; check each brand's chart. - Buy cotton a size up only for sleepers sized 9 months and under. Snug-fit pajamas should fit snugly. - Cotton shrinks a little; wash cold and dry low. - Don't use fabric softener on flame-resistant fleece; follow the care label. Our [baby laundry detergent guide](https://nurseryproof.com/diapering-bath/baby-laundry-detergent) covers detergents. ## Frequently Asked Questions ### How many sleepers does a newborn need? Plan on five to seven. Most newborns go through one or two a night with leaks and spit-up, and you won't be doing laundry every day. ### Are zippers or snaps better for baby pajamas? Zippers, especially two-way zippers, are faster at night: unzip from the feet for a diaper change and the chest stays covered. Snaps are fine but slower in the dark. ### Why do toddler pajamas have to be tight-fitting? U.S. rules for sleepwear in sizes over 9 months require pajamas to be flame resistant or snug-fitting. Snug pajamas are less likely to catch fire because there's less air between fabric and skin. Snug-fitting cotton pajamas carry a hang tag saying so. ### Can my baby sleep in a hat? Not indoors. Babies release heat through their heads, and the AAP warns against overheating during sleep. Use a hat outside and take it off at bedtime. ### Is fleece too warm for baby pajamas? It can be in a heated room. Use fleece in a cold room, and cotton plus a sleep sack when the room is warmer. Check your baby's neck or chest for sweat. ## The Bottom Line For the first nine months, buy a few [Simple Joys 2-way zip sleepers](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07Y2JW91D) or the [Gerber thermal two-pack](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B0DR3CK6ZP), or [Burt's Bees Baby](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B0DPNF21P8) for organic cotton. From 9 months, switch to [Snug-Fit cotton](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07GKVNH2V) or [flame-resistant fleece](https://nurseryproof.com/sleep-nursery/best-baby-pajamas-and-sleepers#product-B07CKZTX2B), and add a sleep sack rather than blankets.
