Give each number a clear meaning
A useful bottle record answers a small question: what happened during this feed? It does not need to turn every bottle into a project.
These fictional numbers illustrate a record, not an amount to offer your baby:
- Started: 24 October, 10:15.
- Offered: 150 mL in the bottle before the feed.
- Left: 40 mL still in the bottle at the end.
- Estimated taken: 110 mL — 150 minus 40, assuming none was spilled.
If milk spilled or the markings were hard to read, that subtraction is less certain. Mark the amount as an estimate in a note. Do not invent a precise correction for a spill or spit-up that you could not measure.
A written line could be: “10:15 — expressed milk, about 110 mL taken; 150 mL offered, 40 mL left.” If the amount taken is unknown, say so rather than copying the amount prepared. The note does not determine whether leftover milk can be stored or used again; follow the appropriate milk-handling guidance separately.
Keep the unit attached to the amount
“Four” is not enough information for a handover. Write mL or the applicable fluid-ounce unit beside it. An ounce by weight is not a fluid ounce, and US and Imperial fluid ounces are different measures.
Cocoon stores bottle amounts in mL; its fl oz option uses US fluid ounces. If you are reading a bottle with a different ounce scale, use its mL markings where available rather than assuming the scales match. You do not need to convert a whole paper history just to record the next feed.
Before comparing a daily total, check that each entry uses the intended unit and that no bottle appears twice. A total of recorded bottles says nothing about an unrecorded feed or the volume transferred at the breast. Our combination-feeding guide shows how to keep those records together without mixing minutes and milk volumes.
Check three details, then save
In Cocoon, open Feed, choose Bottle, and check:
- When: the feed time, including the date if you are entering it later.
- Amount and unit: the estimated amount taken. A remembered amount saves typing, but still needs checking against this feed.
- Contents: formula, expressed milk, mixed or donor milk, as appropriate to the record.
The bottle form has one volume field; it does not subtract leftovers for you. Use that field consistently for the amount taken. Keep extra context in a note if needed. If you do not know the amount, record that uncertainty in a note instead of saving a made-up volume.
Open the saved feed to correct its time or amount. Edit the existing entry rather than adding a replacement that makes the same bottle appear twice. See the breastfeeding and bottle tracker or use the printable feeding log if paper is easier.
Pass on the record, not an assumed next bottle
A short handover can be enough: “Bottle at 10:15, about 110 mL taken; entered in the log.” Agree who enters a paper record into the shared app so both caregivers do not add it.
The previous amount is a memory aid, not a target for the next feed. CDC advises allowing breaks and responding when baby shows fullness, even with milk left in the bottle. Source: CDC bottle-feeding guidance.
Watch your baby as well as the log. CDC’s hunger and fullness guidance explains that babies communicate through movements and sounds; discuss concerns about how much they are taking with their doctor or nurse. Source: CDC hunger and fullness cues.
If a clinician has asked you to track specific details, follow that individual plan. A neat chart cannot establish whether your baby has had enough milk.
