A transfer changes the location, not the history
A batch list may show “freezer” today while saying little about what happened before it arrived there. Preserve the original container or batch reference and expression date/time. Add moves as events rather than replacing the only history with the destination. This guide concerns record continuity, not instructions to move, combine or feed milk.
Use current CDC guidance alongside the record. Its storage FAQ says that moving frozen milk between freezers does not restart its age from the first freezing. Its handling guidance distinguishes thawing and warming events from location changes. For infants with special medical needs, follow the care team’s instructions; a general home-use worksheet cannot determine the appropriate feeding decision.
If your immediate question concerns a fully thawed container, use the thaw-time record guide and the linked CDC source. Do not substitute this transfer worksheet for that different timing question.
One container, three observed events and one visible gap
The following fictional chain uses container M-29. Original expression is recorded as October 27 at 08:00, local time at origin. The table illustrates how to document evidence; it does not recommend this handling sequence or certify the milk as usable.
| Observed event time | From → to | State actually observed | Temperature evidence | Record action |
|---|---|---|---|---|
| Oct 27, 08:15 | Expression area → refrigerator | Container placed inside | No continuous temperature measurement | Retain expression Oct 27, 08:00 |
| Oct 27, 18:00 | Refrigerator → freezer A | Placement observed; freezing completion not observed | No measured container temperature | Record transfer; first fully frozen time unknown |
| Oct 28, 09:00 | Freezer A → freezer B | Frozen appearance observed at departure and arrival | Transit conditions not documented | Preserve the transit evidence gap |
Do not write “continuously frozen” merely because two endpoint observations looked frozen. The missing transit evidence stays missing. Equally, a later note entry time is not necessarily the event time: record both if you are reconstructing the chain afterward. If clocks or time zones differ, label them; do not subtract ambiguous timestamps to produce a confident duration.
The chain has one container, not three new batches. A mistaken duplicate entry can inflate the stash. Check the ID before creating another batch. An unknown observation is not a zero-minute exposure or a normal-temperature reading. No “safe until” result is calculated by this worksheet.
Moving a container and combining milk are different events
A transfer from one storage location to another does not mean two containers were physically combined. If milk actually is combined, the record needs the contributing batch identities and their original histories. Do not average their expression dates or treat the newest contribution as the origin of all the milk.
CDC’s FAQ advises cooling freshly expressed milk before combining it with older cooled or frozen milk, and using the older storage origin when combining cooled milk from different days. Consult the complete current guidance for your situation. This short recordkeeping distinction is not permission to combine milk when the histories or conditions are uncertain.
A physical handoff adds another question: what was communicated to the receiving caregiver? Keep that communication separate from what you personally observed. For a later caregiver transfer, the daycare handoff guide provides a different artifact. Do not add a child’s name or private health details to a worksheet unless the intended recipient actually needs them.
MilkVault records location; the companion chain preserves more detail
The current MilkVault listing describes pump logs, batches by expression date/location, bottle records, stash totals and Premium CSV export. It says dates and estimates do not determine whether milk is safe. Current source stores a batch’s present location and expression time; a complete transfer-temperature history was not verified.
Changing an app location must not be interpreted as resetting earlier handling or validating a new storage allowance. Keep this external event chain when you need provenance beyond the current batch fields. Exported records are a copy of recorded data, not proof that conditions were measured or that a healthcare professional approved them.
If the history is incomplete, preserve the gap and use current official guidance or your pediatrician/lactation professional for the actual feeding question. The goal here is an honest record that helps a conversation. For the broader stash list, return to the freezer-stash log.

Use the CSV in Numbers, Excel or a spreadsheet editor. The fictional sequence is a recordkeeping example, not a handling recommendation or safety determination. Replace them with your own observations. The CSV is separate from the app and no email is required.
Questions answered
Does moving milk to another freezer restart its age?
No. CDC’s FAQ says to count from the first freezing when moving frozen milk between freezers. Preserve that origin and the actual handling history.
Does a freezer entry prove the milk stayed frozen in transit?
No. Current location and endpoint observations are not a continuous temperature record. Mark missing transit conditions as unknown.
Can this worksheet decide whether milk is safe to feed?
No. It organizes provenance and uncertainty. Use current official guidance and the relevant care team for feeding decisions.
