Federal safety officials warned on Thursday, Nov. 12, that a white Mommy & Me Pack & Play mattress can leave a gap large enough to trap an infant when used in an incompatible play yard. The Consumer Product Safety Commission says owners should stop using the affected mattress in those play yards immediately and dispose of it.

Check both model numbers

The mattress model is MNM-PNPMAT-WHT. It measures about 38 by 26 inches. Look for the Mommy & Me name and the model number on the mattress labels. The agency's notice includes photos of both labels. The warning excludes use with the Mommy & Me Play Yard model MNM-PMP-BLCK. Check the play yard's label as well before relying on that exception.

About 13,278 mattresses are involved. Amazon sold the mattresses separately from July through September 2025 for about $36. CPSC says other sellers may also have offered them. The agency listed no reported injuries and said Mommy & Me had not agreed to a recall or an acceptable remedy. It asks owners to dispose of affected mattresses and keep them out of resale and donation.

If you need a replacement

CPSC says a replacement mattress should specify compatibility with the exact play-yard or crib model. The American Academy of Pediatrics recommends a firm, flat sleep surface for infants, with a fitted sheet and no extra padding. A mattress can look close to the right size and still leave room for a baby's face to become trapped against the side.
