An “overnight” label is not a promise of uninterrupted sleep or a reason to postpone care. Begin with the actual product instructions and the observation you need help with.
Describe what is happening
Note the product name, size information from the current package, where the leak appeared and any recent changes. Distinguish a fit question from a cloth-component care question or a concern about the baby's skin or health. A wet sheet alone does not tell this guide which explanation applies.
Check the manufacturer's fitting instructions and any use limits. Do not apply a generic “always size up” rule or add a booster, second diaper or other accessory without appropriate product instructions. If a cloth system is involved, identify the exact components and their care requirements. Keep the record specific enough for the manufacturer to understand the question.
Separate the product problem from the care decision
The American Academy of Dermatology's diaper-rash guidance recommends promptly changing wet or dirty diapers. Ask your baby's clinician about individual nighttime care, skin problems, unusual output or other health concerns. This planning record cannot determine when it is appropriate for your baby to sleep without a change.
Do not restrict feeds or fluids to make a diaper last longer, change a baby's sleeping position to direct a leak or add loose materials to the sleep space. Keep sleep arrangements consistent with the CPSC's safe-sleep guidance and any individual medical advice. A product's advertised duration is not a care instruction for a particular child.
Prepare the practical handoff
Keep the supplies for a needed change in the usual adult-controlled changing arrangement, along with replacement clothes and bedding. Agree which adult takes over when help is needed and where used items go. Record the observation for the next conversation instead of trying several unsupported modifications in one night.
An illustrative troubleshooting note
The replacement pack changed two things
A household notices leaks after buying a different product and changing size at the same time. Its note records both changes, the current package instructions and where the leakage appears. The caregivers check the manufacturer's fitting guidance and ask about the unresolved product question. They keep their existing care and sleep-safety arrangements, prepare clean replacements and take any skin or health concern to the baby's clinician. They do not claim that an extra absorbent layer or an advertised hour count solves the problem.

Before buying a large supply, check size and package assumptions before stockpiling. For reusable items, record care instructions for nighttime components.
