What a pumping session records
- Left and right output, recorded separately rather than as one total.
- Where it went — the fridge, the freezer, or straight into a bottle now — and from the oldest session in each, when it wants using: “Fridge milk from 12 Sep: use by 16 Sep”. It is not a running count of what you have banked; it is the date on the oldest bag, worked out for you.
- Time of day, which is what makes the pattern readable later — the 4am session is not the 4pm one.
Reading supply against intake
Bottles are logged as breast milk or formula, so the feed charts can separate them. Put that next to the week’s pumping output and the trend is visible without a spreadsheet: output sliding away from intake, a session you have quietly dropped, a day where the combination worked. Ask will do the arithmetic out loud — “how much did she take yesterday?” — from your own records.
Logging at 3am with one hand
A pumping session can be started from the quick-log panel, and the running timer stays on the Lock Screen and in the Dynamic Island while you do something else. If you forgot to start it, log it afterwards: switch off “Still pumping” and set when it started and ended.
