Incident Overview

On September 20, 2026, a consumer filed an incident report detailing a distressing experience with Millie Moon Size 5 diapers. According to the report, the consumer’s daughter developed severe, welted blisters after wearing the diapers. The parent attributes this reaction to a recent change in the diaper’s formula by the manufacturer, Zuru Inc. This concern is not isolated, as the consumer noted that multiple other parents have reported similar adverse reactions in reviews on the Target App, suggesting a potentially widespread issue. The child’s blistering skin condition only began to heal after the parent discontinued use of the Millie Moon diapers and switched to a different brand. The incident highlights a potential manufacturing change that may have significant implications for sensitive infant skin.

Safety Concerns

The reported incident raises several significant safety concerns for infants and toddlers using Millie Moon Size 5 diapers:

  • Immediate Dangers: The most immediate danger is severe skin irritation, manifesting as welted blisters. Such conditions can cause intense pain, discomfort, and crying in infants. Blisters can break open, leading to raw skin and increasing the risk of secondary bacterial or fungal infections, which could require medical treatment.
  • Long-Term Risks: Persistent irritation or recurring infections could potentially lead to long-term skin sensitivities, scarring, or hyperpigmentation in severe cases. Frequent exposure to irritants can also exacerbate existing skin conditions like eczema. The discomfort can also disrupt sleep and overall well-being for the child and cause significant distress for parents.
  • Who Might Be Affected: Infants and toddlers using Millie Moon Size 5 diapers are directly at risk, especially those with sensitive skin, allergies, or pre-existing dermatological conditions. Parents and caregivers are also affected by the emotional distress of seeing their child in pain and the added burden of seeking medical attention and finding alternative products.
  • Property Damage Potential: There is no direct property damage potential associated with this type of incident.

What Consumers Should Do

If you are a parent or caregiver using Millie Moon Size 5 diapers, particularly if purchased from Target, and have observed any skin reactions in your child, please take the following actions:

  • Immediate Steps to Take:
  • Discontinue use of Millie Moon Size 5 diapers immediately if your child develops any signs of skin irritation, redness, rash, or blistering.
  • Gently clean the affected area with mild soap and water, and apply a pediatrician-recommended diaper rash cream or barrier ointment.
  • Consult your pediatrician promptly if your child develops severe blistering, open sores, signs of infection (such as fever, pus, or increased redness), or if the rash does not improve within a day or two of discontinuing the product.
  • How to Check if They Own the Affected Product:
  • Inspect your current supply of Millie Moon Size 5 diapers. While there is no specific lot number provided in this report, be aware that any recent purchase might be from the batch potentially affected by a formula change.
  • Carefully monitor your child’s skin after each diaper change for any unusual redness, irritation, or bumps.
  • Prevention Measures:
  • Consider performing a “patch test” by using one of the new diapers for a short period and closely monitoring your child’s skin before committing to a full pack.
  • If you have concerns, consider switching to an alternative trusted diaper brand until more information becomes available from the manufacturer.
  • Always ensure regular diaper changes to minimize skin exposure to moisture and potential irritants.
  • Reporting Procedures:
  • If your child has experienced a similar reaction, report the incident to Zuru Inc., the manufacturer of Millie Moon diapers.
  • Contact Target, the retailer, to make them aware of the issue and check for similar reports or recalls.
  • File a detailed incident report with the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report helps identify patterns and prompt further investigation.
