A new class action claims Millie Moon luxury diapers cause rashes and burns on babies' skin.

Noah Ornelas filed a class action lawsuit on Oct. 22, 2026, against Zuru LLC and Zuru Consumer Brands LLC, the companies behind Millie Moon Luxury Diapers, in the U.S. District Court for the Northern District of Illinois.

The lawsuit alleges Zuru markets the diapers as safe for sensitive skin yet they cause rashes and burns on the infants and children who wear them.

Millie Moon's label claims

The filing claims the packaging advertises the diapers as dermatologically tested. Ornelas says he bought the diapers for his children because he believed they were safe. He alleges he would not have bought them had he known about the defect.

Consumer complaints

The lawsuit cites 584 reports mentioning Millie Moon on saferproducts.gov, the Consumer Product Safety Commission's public incident database. The earliest dates to July 2023 with a surge in March 2026, according to the complaint.

Parents reportedly describe diaper-area skin that turned thin and extremely red, oozed or bled, and developed welts, blisters, open wounds and peeling. In many accounts, the irritation allegedly resisted treatment while the child kept wearing Millie Moon and cleared up only after the family switched brands, the proposed class action claims.

Several longtime Millie Moon customers say they did not experience problems with the diapers until a recent product change, according to the complaint. The lawsuit cites a company spokesperson's acknowledgment of a recent update to the diaper's outer layer that they described as visual only.

Zuru refuses to recall the diapers, the filing contends. Its replies to one-star reviews point to the product's safety certifications, but the complaint claims they offer no real remedy.

The legal claims

The lawsuit brings eight claims:


  • Illinois Consumer Fraud Act, which bars deceptive business practices

  • Fraudulent concealment, which applies when a company conceals a known defect from buyers

  • Breach of the implied warranty of merchantability, which requires products to work for their ordinary purpose

  • Unjust enrichment, which bars a company from keeping money it gained unfairly

  • Negligent design, negligent failure to warn and negligence, which cover a company's duty to make safe products and warn buyers of risks

  • Negligent misrepresentation, which includes false statements a company should have known were wrong

The consumer fraud claim only covers people who bought the diapers in Illinois. Ornelas seeks compensation for buyers' losses, refunds, the profits Zuru made from the sales and punitive damages along with a court order requiring a recall and better product testing.

What the lawsuit means for Millie Moon buyers

The proposed class covers anyone in the United States who bought Millie Moon diapers. As of this writing, there is no settlement, no claims process and no money available.
