What Not to Put in a Crib: Bumpers, Pillows, and More

A crib looks surprisingly empty when it is set up correctly. There is a mattress, a fitted sheet, and nothing else — no bumper, no pillow, no blanket, no stuffed animal, and nothing on the wall directly above it. That bare look is not a style choice. The list of what not to put in a crib is short, and it is the same list pediatric and consumer-safety agencies publish for every sleep, naps included.

The reasons behind each item matter, because most of these products are still sold in stores and still photographed inside cribs. If you are furnishing the whole room, our guide to setting up a safe nursery room covers the wider layout; this article focuses on the crib itself and the space immediately above it.

What Not to Put in a Crib: The One Rule Behind Every Item

Every item on this list is soft, loose, or hanging — three qualities that share the same problem. Soft bedding can cover a baby's face, and newborns do not have the neck strength or the reflexes to move it away. Loose items shift position during the night. Anything mounted above the crib can fall.

The American Academy of Pediatrics (AAP) describes the ideal sleep surface as firm, flat, and bare, with a fitted sheet as the only covering. The CDC summarises the same 2022 AAP recommendations: babies should sleep on their back, on a firm flat surface, in their own separate sleep space, with no soft bedding. Health Canada puts the design advice more bluntly — decorate the room, not the crib.

This is not about buying a better product. It is about removing things, which is genuinely good news: the recommended version of a crib is also the least expensive one.

Crib Bumpers: Why They Are Banned, Not Just Discouraged

What bumpers were designed to do

Bumpers were sold to stop small limbs from slipping between crib slats and to soften bumps against the rails. They look protective, and that is exactly why so many parents still install them.

Why they are a problem

A padded bumper creates a soft pocket along the inside of the crib, where a baby's face can come to rest. The ties used to attach bumpers add a strangulation risk of their own. And because a bumper sits across the sides of the crib, it works against one of the reasons crib slats exist in the first place.

The AAP recommends against bumper pads of every kind, and its guidance does not carve out an exception for mesh or "breathable" versions.

The legal status

In the United States this is no longer only a recommendation. The federal crib bumper ban arrived with the Safe Sleep for Babies Act of 2021 (H.R. 3182), signed into law on 16 May 2022, which prohibits the manufacture and sale of crib bumpers and inclined sleepers for infants. Some states, including Maryland, had restricted bumpers years earlier.

If you are buying a used crib and it comes with a bumper, treat the bumper as something to remove rather than reuse.

What to do instead

If your concern is limbs slipping between the slats, check the crib itself rather than adding padding. Under the federal crib standards, slats must be no more than 2⅜ inches (about 6 cm) apart — narrow enough that a baby's body cannot pass through. A crib that meets the current standard does not need padding to keep a baby inside it.

Pillows, Blankets, Stuffed Animals, and Loveys

Crib with loose bedding, items to remove before sleep
Items to remove before sleep: loose blankets, pillows and toys do not belong in an infant sleep space.

The rule for soft items is the same as for bumpers, and it applies from the first night home: nothing soft goes in the sleep space.

  • Pillows. Even flat "newborn pillows" and head-shaping cushions are soft bedding. A baby does not need a pillow, and one can cover the face if the baby turns.
  • Blankets. A loose blanket can end up over the head. If you want warmth, use a correctly sized sleep sack or wearable blanket instead.
  • Stuffed animals and loveys. These are fine in a play area or on a shelf. They are not for the crib while a baby is sleeping.
  • Positioners and wedges. These are marketed to hold a baby in place or to shape the head, and the AAP advises against using them for sleep.

If your baby seems cold, the practical fix is a sleep sack plus an appropriate room temperature, not an extra layer in the crib.

Positioners, Loungers, and "Baby Nest" Products

Infant loungers, nests, docks, and similar support cushions deserve their own section, because they are so often placed inside cribs and bassinets.

These products are shaped to cradle a baby, which is exactly what makes them unsuitable for sleep — a baby's face can end up pressed against the raised edges. Regulators have moved on this category too: the CPSC's mandatory federal safety standard for infant support cushions (16 CFR 1243) took effect in 2025, adding requirements aimed at suffocation and entrapment hazards, along with clearer labelling.

The practical rule is simple. A lounger or nest is not a sleep surface, it does not belong inside a crib or bassinet, and it should never be used for sleep.

Nothing Above the Crib: Shelves, Mobiles, and Cords

Hanging nursery toys, keep out of reach
Keep hanging toys and cords out of reach. Remove mobiles by 5 months or sooner if the baby pushes up or can reach them.

This is the part of crib safety that gets the least attention, and it is the reason one parent's warning post spread so widely: an object falling into a crib is a real hazard, and it happens in the one area most parents have already checked.

Shelves, frames, and mirrors

Do not hang framed pictures, mirrors, shelves, or heavy decor directly over a crib. Anything that can fall should move to another wall. The same logic applies to furniture: dressers, shelves, and changing tables should be anchored to the wall so they cannot tip, and they should not be positioned so that a child can use the crib as a step to reach them. Our guide to safe clearances for cribs, bassinets, and changing areas walks through the spacing in more detail.

Mobiles

Keep mobiles securely attached and out of reach. Remove them by 5 months or sooner if your baby begins pushing up on hands and knees or can reach them. Follow any earlier stop-use instruction supplied with the mobile.

Cords, monitors, and windows

Keep baby monitor cords, lamp cords, and window-covering cords well away from the crib; cords are a strangulation hazard, and the CPSC advises placing cribs away from windows for exactly that reason. If you use a camera, mount it so that no part of the cord can reach into the crib, and re-check it whenever you move furniture.

It is also worth keeping the crib out from directly under a window, where a child can reach blinds or use the sill to climb.

The Bare Crib Checklist

Everything that belongs in a crib:

  • A firm mattress that fits the crib frame tightly, with no gaps at the corners.
  • A fitted sheet made for that mattress size.
  • Nothing else.

Everything that should stay out:

  • Bumpers and mesh liners
  • Pillows and head-shaping cushions
  • Blankets, quilts, and comforters
  • Stuffed animals, dolls, and loveys
  • Positioners, wedges, loungers, and nests
  • Toys and activity gyms
  • Extra mattresses, toppers, or padding

Two quick checks are worth doing before the first night. Press down on the mattress: it should feel firm, not compressible. Then try to slide two fingers between the mattress edge and the crib frame — if they fit easily, the mattress is too small for the crib.

How to Set Up a Safe Crib: 6 Steps

  • Check the crib's standard. Look for a crib built to the current federal safety standard, with slats no more than 2⅜ inches apart and no drop-side rail.
  • Fit the mattress. Confirm there are no gaps wider than two fingers between the mattress and the frame.
  • Set the mattress height. Start at the higher setting for a newborn, and lower it as soon as your baby can sit up or push up on hands and knees.
  • Dress the bed with one sheet. A fitted sheet, and nothing more.
  • Clear the space above. Move frames, shelves, and mirrors to another wall, and take down the mobile once your baby becomes mobile.
  • Route the cords. Keep monitor, lamp, and blind cords out of reach, and pull the crib away from the window.

FAQ

Are crib bumpers safe?

No. The AAP recommends against bumper pads, and the federal Safe Sleep for Babies Act prohibits the manufacture and sale of crib bumpers in the United States. Mesh or "breathable" bumpers are not an exception to that guidance.

Can I put a pillow in a crib for a newborn?

No. A newborn does not need a pillow, and soft bedding of any kind can cover a baby's face during sleep. The recommended setup is a firm mattress with a fitted sheet.

What if my baby is cold without a blanket?

Use a correctly sized sleep sack or wearable blanket rather than a loose blanket, and check the room temperature. A sleep sack keeps a baby warm without adding loose fabric to the crib.

When should I remove the mobile from the crib?

Keep mobiles securely attached and out of reach. Remove them by 5 months or sooner if your baby begins pushing up on hands and knees or can reach them. Follow any earlier stop-use instruction supplied with the mobile.

Can I put a baby lounger or nest inside a crib?

No. Loungers, nests, and similar support cushions are not sleep surfaces, and they should not be placed in a crib or bassinet for sleep.

Are mesh crib liners safer than padded bumpers?

They are not recommended either. The AAP's advice is to keep the sides of the crib clear rather than to swap one soft liner for another.

Maydolly Bassinets: The Same Bare-Space Principle

The bare-space rule does not stop at the crib. Many parents keep a smaller sleep space beside the bed for the first months, and the same logic applies there: a firm mattress that fits tightly, a fitted sheet, and nothing loose.

That principle shapes how Maydolly bassinets are put together.

Maydolly C03 Plus 3-in-1 Adjustable Bassinet

The Maydolly C03 Plus 3-in-1 Adjustable Bassinet ships with a fitted foam mattress and a supportive board, so the sleep surface is the one designed for the frame rather than an add-on. Its mesh side panels keep the sides visible, and the foldable mosquito net attaches with a zipper rather than being draped over the side. There is a storage basket underneath for the things you want within reach, and one storage bag for the bassinet itself when it is folded away.

Use the C03 Plus only within the weight and developmental limits for the specific configuration in its manual. A marketing age range is not permission to keep using a bassinet after a developmental stop-use milestone.

Maydolly 506 Smart Electric Cradle

The Maydolly 506 Smart Electric Cradle combines bassinet and playpen configurations with cry detection, five sway levels, built-in sounds, height adjustment and wheels. Follow the manual’s separate limits for each mode; a single weight limit should not be applied to both modes.

Whichever sleep space you choose, the setup stays the same: firm, flat, fitted, and clear. You can compare the full range of bassinets and cradles on our collection page.

Final Thoughts

What not to put in a crib comes down to three categories: soft, loose, and hanging. No bumpers, no pillows, no blankets, no stuffed animals, no positioners, and nothing mounted above the sleep space. Add a firm, well-fitting mattress, a fitted sheet, and a crib built to the current standard, and you have a safe crib setup.

The bare crib looks unfinished, and that is precisely what pediatric and consumer-safety agencies describe. Keep the decor on the walls and the shelves, and keep the sleep space empty.
