June 15, 2026 — A recent incident report details a distressing case involving Millie Moon Size 3 diapers, where a child reportedly developed severe diaper rash, welts, blisters, and bleeding shortly after switching to the new size. The incident has led to multiple urgent care visits for the affected infant.
Product Details
Product: Millie Moon Size 3
Incident Overview
According to an incident report filed on May 27, 2026, a consumer reported that their child experienced a severe adverse reaction after transitioning from Millie Moon Size 2 to Millie Moon Size 3 diapers. Approximately three weeks prior to the report date, the child switched to the larger size. Shortly thereafter, the child began to suffer from a “horrible diaper rash” that progressed to include welts, blisters, and bleeding. The severity of the rash necessitated multiple urgent care visits for medical attention. The consumer’s report indicates the onset of these painful symptoms occurred after the introduction of Size 3 diapers.
Safety Concerns
The reported incident raises significant safety concerns regarding the Millie Moon Size 3 diapers, particularly for infants with sensitive skin or those previously accustomed to other sizes or brands.
- Immediate Dangers: The most pressing danger is severe skin irritation, including painful rashes, welts, and blistering, which can lead to open wounds and bleeding. Such conditions are incredibly uncomfortable for an infant and can disrupt sleep, feeding, and overall well-being.
- Risk of Infection: Open wounds and broken skin, as described in the incident, are highly susceptible to bacterial or fungal infections. These secondary infections can complicate recovery, require more intensive medical treatment, and in severe cases, could lead to systemic issues if not properly managed.
- Allergic Reactions/Chemical Irritation: The sudden onset and severity of the rash after switching to a different size of the same brand could indicate a batch-specific issue, a material change in the Size 3 product, or a potential allergic reaction to a component unique to or more concentrated in the Size 3 diapers.
- Who Might Be Affected: Infants and toddlers who use Millie Moon Size 3 diapers are potentially at risk. Those with pre-existing skin sensitivities or allergies may be particularly vulnerable to adverse reactions.
- Long-term Risks: While the primary focus is on immediate relief, severe and prolonged skin irritation can potentially lead to scarring or persistent skin sensitivity in the affected area, impacting the child’s comfort and health long-term.
- Property Damage Potential: In this specific incident, there is no direct property damage reported beyond potential medical costs and product replacement.
What Consumers Should Do
If you are a consumer using Millie Moon Size 3 diapers or any other diaper and observe similar symptoms in your child, please take the following immediate steps:
- Discontinue Use Immediately: Stop using the suspected diapers and switch to a different brand or size, especially if your child exhibits any signs of rash, irritation, welts, or blistering.
- Seek Medical Attention: If your child develops a severe rash, welts, blisters, or bleeding, consult a pediatrician or seek urgent medical care immediately. Do not attempt to self-diagnose or treat severe conditions.
- Document Everything: Take clear photographs of the rash, welts, or blisters, and keep a detailed record of symptoms, medical visits, and any conversations with healthcare providers. Retain the affected diapers and packaging, if possible, for potential inspection.
- Check Other Diapers: Examine other diapers in the package for any visible defects, changes in material, or unusual odors.
- Report the Incident: File a detailed incident report with the U.S. Consumer Product Safety Commission (CPSC) at SaferProducts.gov. This helps authorities track potential hazards and gather data for investigation.
- Contact Manufacturer and Retailer: Reach out to Zuru Inc., the manufacturer of Millie Moon diapers, and Target, the retailer where the product was purchased, to report your experience.
