A crib does not have one set expiration date. Replace it when its age, condition, missing information, or recall status makes it hard to confirm that it can be used exactly as designed.
Stop using the crib right away if it has broken or missing parts, loose joints, cracked slats, damaged mattress supports, an unstable frame, or a side that will not stay locked. Cribs with these problems can form dangerous gaps or collapse. Do not keep using the crib while waiting for parts.
Signs It Is Time to Replace a Crib
If replacing the crib also requires a new compatible mattress and airflow matters, compare options in the breathable crib mattress roundup.
The crib has been recalled
Check the crib’s manufacturer, model number, and date of manufacture against the current U.S. Consumer Product Safety Commission recall database. This is especially important for a used crib, a hand-me-down, or a crib stored between children.
Follow the recall notice exactly. Depending on the recall, the manufacturer may offer an approved repair, replacement, refund, or disposal instructions. Do not sell, donate, or pass along a recalled crib.
It is a drop-side crib
A traditional drop-side crib has a side rail that moves up and down. These cribs do not meet the U.S. crib requirements that took effect on June 28, 2011.
Attaching homemade brackets or locking the side in place does not turn an old drop-side crib into a crib that meets the newer standard. Current CPSC resale guidance says drop-side cribs should not enter the used marketplace, even when the moving side has been immobilized.
Parts are missing, loose, cracked, or broken
Replace the crib, or stop using it until the manufacturer provides an approved remedy, when you find:
- Missing screws, bolts, brackets, or locking parts
- Hardware that keeps loosening
- Cracked, split, warped, or missing slats
- A sagging, bent, or damaged mattress support
- Loose corner joints
- Sharp edges, splinters, or exposed fasteners
- A frame that rocks or twists after correct assembly
- A folding crib that does not lock fully open
Missing or damaged hardware can create gaps between crib parts. Incorrect assembly and broken slats can also create entrapment hazards.
Do not replace original hardware with a screw or bolt from a hardware store. The size may look right while the strength, thread pattern, length, or locking function is wrong. Contact the crib manufacturer for the exact approved part.
The crib cannot be assembled from its instructions
A safe-looking crib may still be assembled incorrectly. This is more likely after a move, long-term storage, or repeated use by several families.
Stop using the crib when:
- The instructions are missing and cannot be obtained
- Parts cannot be identified
- The mattress support position is unclear
- Hardware is left over after assembly
- A part does not line up as shown
- The assembled crib has unexplained gaps or movement
The American Academy of Pediatrics advises against using a crib that has no instructions, is missing hardware, or is broken.
You cannot identify the crib
A manufacturer label or permanent marking may include the brand, model, and manufacture date. This information helps you check recalls, obtain instructions, and order correct parts.
Consider replacing a crib when the label is missing or unreadable and you cannot confirm:
- Who made it
- Which model it is
- When it was made
- Which instructions belong to it
- Whether it has been recalled
- Whether replacement parts are still available
A crib should not be treated as safe simply because it looks sturdy.
The crib was made before current U.S. requirements took effect
In the United States, stronger federal requirements for full-size and non-full-size cribs took effect on June 28, 2011. The requirements strengthened areas such as hardware, slats, mattress supports, side construction, testing, and labeling.
CPSC resale guidance says cribs manufactured before that date should not be resold unless there is written proof that the crib meets the applicable standard. For a family deciding whether to use an older crib, the practical choice is usually to replace it when compliance cannot be confirmed.
The manufacture date matters more than the date a relative bought the crib. A crib stored at a grandparent’s house may be older than anyone remembers.
The mattress no longer fits the crib correctly
Replacing the mattress and replacing the crib are separate decisions. First identify which part is causing the fit problem.
The mattress should be the size specified in the crib instructions and should fit tightly without an entrapment gap. Do not try to fix a loose fit with rolled towels, foam, boards, blankets, or padding.
Replace or stop using the setup when:
- The crib frame has spread or changed shape
- The mattress support is bent
- The correct mattress leaves a gap
- The mattress is not approved for that crib size
- The crib and mattress cannot be matched to their instructions
A firm, tight-fitting mattress is part of a proper crib setup.
The child has outgrown the crib
A child outgrowing a crib does not always mean the crib is worn out. It means the crib is no longer the right configuration for that child.
Follow the crib manufacturer’s limits and transition instructions. Stop using the crib configuration when the child reaches a listed height or developmental limit, can climb out, or can otherwise defeat the crib sides.
A convertible crib may be changed into a toddler-bed configuration only when the manufacturer permits it and the correct conversion parts are used. Do not remove a crib side and create a homemade toddler bed unless the instructions specifically allow that setup.
Developmental timing and product configuration are separate questions. The crib instructions control which configurations are allowed. A child’s health professional can help with individual developmental concerns.
Does a Crib Need to Be Replaced After Every Baby?
Damage, sagging, or contamination may meet the broader crib mattress replacement signs instead of calling for another adjustment.
Not automatically.
A crib may be used for another child when all of the following are true:
- It meets the current rules that apply where you live
- It has not been recalled
- Every original part is present
- The manufacturer’s instructions are available
- It can be assembled exactly as directed
- The frame, slats, support, and hardware are undamaged
- The correct mattress fits tightly
- The child remains within the crib’s limits
Inspect the crib before each new period of use. Storage conditions matter. Moisture can damage wood or metal. Hardware may be lost during a move. Repeated assembly can also wear connections.
How to Check a Used or Hand-Me-Down Crib
For a hands-on edge check, use the crib mattress fit checks before deciding that a sleep surface is compatible.
A used crib needs more than a quick shake test.
1. Find the identification label
Record the manufacturer, model number, and manufacture date. Without this information, checking recalls and finding the correct instructions may be difficult.
2. Check current recalls
Search by the manufacturer and model. Do not rely on the previous owner saying that the crib was never recalled. Recall information can be announced after a product was purchased.
3. Obtain the exact instructions
Confirm that the instructions match the model. Check the parts list, assembly order, mattress-support positions, permitted conversions, and child-use limits.
4. Count and inspect every part
Look for original bolts, screws, washers, brackets, support pieces, locking parts, and conversion components. Do not combine parts from two similar-looking crib models.
5. Assemble it completely
A crib cannot be judged properly while folded, boxed, or partly assembled. Check for movement, gaps, cracking, worn holes, and loose connections after following the full assembly process.
6. Confirm the mattress match
Use the mattress size stated on the crib label or in its instructions. The mattress should be firm, flat, and tightly fitted.
A retailer description, online listing, or customer review is not proof that a mattress fits a particular crib.
When a Manufacturer Repair May Be Appropriate
The crib mattress size guide explains how labels, measured dimensions, and model compatibility work together.
Replacement of the entire crib may not be necessary when the manufacturer confirms that a genuine replacement part or official repair is available.
An approved remedy may be reasonable when:
- The exact model can be identified
- The crib is not under a stop-use recall
- The manufacturer supplies the part
- The instructions explain the repair
- No wood, frame, slat, or support damage is present
- The crib is stable after the approved work
Do not glue cracked slats, drill new holes, add corner braces, weld the frame, or create homemade locking parts. These changes may affect how the crib handles movement and weight.
When the manufacturer is no longer operating or cannot supply the correct part, replacing the crib is usually the practical choice.
Check the Crib Again After Moving or Storage
A crib should be inspected after it has been:
- Taken apart for a move
- Stored in a garage, basement, attic, or shed
- Shipped
- Lent to another household
- Reassembled in a grandparent’s home
- Converted and later changed back
Use the instructions each time. Do not depend on memory from the first assembly.
After assembly, check every connection and make sure the mattress support is attached in all required places. Continue to inspect the crib regularly for loose joints, missing parts, cracks, or sharp areas.
Mini Cribs, Portable Cribs, Playards, and Travel Cribs
These products are not interchangeable.
A mini crib may be covered by non-full-size crib requirements, but its dimensions and mattress are model-specific. Identify the exact model before choosing a mattress or replacement part.
A playard or travel crib may use a thin, firm floor pad that is part of the product’s tested design. Do not add a standard crib mattress, foam pad, topper, or aftermarket mattress unless the sleep-space manufacturer explicitly approves it for that exact model.
Replace or stop using a portable sleep space when its instructions require it or when you find problems such as:
- Torn or detached mesh
- A damaged floor pad
- Broken hinges or rails
- Locks that do not engage
- Missing straps or clips
- A frame that folds unexpectedly
- Parts from a different model
CPSC guidance says mesh-sided products should have securely attached mesh without tears, holes, or loose threads.
A Simple Replace-or-Keep Checklist
Keep using the crib only when you can answer yes to every question:
- Can I identify the manufacturer, model, and manufacture date?
- Do I have the exact instructions?
- Does it meet the rules that currently apply where I live?
- Is it free from recalls or active stop-use warnings?
- Is every original part present?
- Is there no cracked, warped, bent, or damaged structure?
- Does every lock and connection work correctly?
- Is the crib stable after proper assembly?
- Does the specified mattress fit tightly?
- Is my child still within the manufacturer’s limits?
One “no” does not always mean the crib must be thrown away. It does mean the crib should not be used until the issue is resolved through current official guidance and the manufacturer.
Frequently Asked Questions
Do cribs have an expiration date?
Most cribs do not have a simple expiration date like a car seat may have. Age still matters because standards change and parts can wear, loosen, or disappear. Replace the crib when you cannot confirm its compliance, recall status, instructions, parts, condition, or approved use.
Is a 10-year-old crib safe to use?
Do not decide by age alone. Check the manufacture date, model, recall status, current local rules, instructions, hardware, and structural condition. In the United States, a crib made before June 28, 2011 should generally be replaced unless there is written proof that it meets the applicable federal requirements.
Can I use a crib with one missing screw?
No. Stop using it until the exact manufacturer-approved replacement part is installed according to the instructions. A similar screw from a hardware store may not have the correct length, strength, or locking design.
Should I replace a crib after moving?
Not automatically. Reassemble it from the exact instructions and inspect every part. Replace it or contact the manufacturer when hardware is missing, holes are worn, joints stay loose, the frame is damaged, or the crib cannot be made stable.
Can an antique crib be used with a new mattress?
A new mattress does not correct problems with an old crib. Antique cribs may have outdated spacing, decorative openings, damaged materials, missing hardware, or no way to verify compliance. Use a sleep space that meets current requirements instead of modifying an antique crib for infant sleep.
When should a child move from a crib to a toddler bed?
Follow the crib manufacturer’s child limits and conversion instructions. Transition when the child reaches a stated limit, can climb out, or no longer remains safely contained. Use only the toddler-bed configuration and conversion parts approved for that exact crib.
Do I need to replace the crib mattress when I replace the crib?
Possibly. The mattress must be the correct size and type for the new crib. Do not assume an old mattress fits because both products are called full-size or mini. Check the new crib’s label and instructions, then inspect the mattress separately for fit, firmness, damage, and care requirements.
The standard crib dimensions guide separates interior mattress space from the crib's outside measurements.
Keep the decision within a safe crib mattress setup: firm, flat, snugly fitted, and free of added padding.
The crib placement safety guide covers nearby walls, windows, cords, heat sources, and furniture after the mattress setup is correct.
Use the flat crib mattress guide to distinguish a level sleep surface from one that sags, tilts, or lifts at the edges.
