June 12, 2026 — Consumers are advised to exercise caution regarding certain batches of Millie Moon size 4 diapers following reports of severe blistering diaper rash in infants. The incident specifically targets diapers manufactured between December 2025 and February 2026.
Product Details
Incident Overview
An incident report filed on May 26, 2026, details concerns surrounding Millie Moon size 4 diapers. According to the report, diapers from specific manufacturing dates—December 2025 through February 2026—have been associated with instances of severe blistering diaper rash in infants. While the exact cause of the rash is currently under investigation, the consistent nature of the reports across this manufacturing window suggests a potential defect or contamination within these particular batches. Parents using these diapers have reported their children developing painful blisters and irritation in the diaper area, indicative of a significant adverse reaction beyond typical diaper rash.
Safety Concerns
The reports of severe blistering diaper rash raise significant safety concerns for infants.
- Immediate Dangers: Severe blistering diaper rash can cause extreme discomfort and pain for infants. Blisters can break, leading to open wounds that are highly susceptible to secondary bacterial or fungal infections, potentially requiring medical intervention such as antibiotics or antifungal treatments. The pain associated with such a rash can also lead to sleep disturbances, irritability, and feeding difficulties in affected babies.
- Long-Term Risks: Persistent or severe infections, if not properly treated, could potentially lead to more serious skin conditions or complications, although long-term scarring from typical diaper rash is uncommon. Repeated exposure to an irritant could also heighten skin sensitivity.
- Who Might Be Affected: Infants and toddlers wearing Millie Moon size 4 diapers manufactured between December 2025 and February 2026 are primarily at risk. Given the delicate nature of infant skin, they are particularly vulnerable to chemical irritants or material defects.
- Property Damage Potential: While there is no direct property damage reported, the incident could lead to increased consumption of topical creams, medical visits, and potential hospital stays, creating financial burdens for affected families.
What Consumers Should Do
Consumers whose infants use Millie Moon size 4 diapers should take immediate action:
- Immediate Steps to Take: If your child is experiencing a severe blistering rash, discontinue use of the affected diapers immediately. Seek prompt medical attention from a pediatrician or healthcare provider for diagnosis and treatment. Keep any packaging or remaining diapers as they may be useful for investigation.
- How to Check if They Own the Affected Product: Check the manufacturing date on your package of Millie Moon size 4 diapers. The affected batches are those manufactured from December 2025 to February 2026. This information is typically found on the diaper packaging, often near the barcode or on the plastic wrapper.
- Prevention Measures: Until further information is available, consider switching to an alternative brand or different batch of diapers. Closely monitor your child for any signs of rash or irritation when using new products.
- Reporting Procedures: If your child has experienced a similar severe blistering rash after using Millie Moon size 4 diapers from the specified manufacturing dates, please report the incident to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Providing detailed information, including photos and medical records, can aid in further investigation.
