A page from our bottle log
17 October: 910 ml offered, 580 ml drank.
One day from our own log. The bottles held 910 ml (about 31 fl oz). Our baby drank 580 ml (about 19.6 fl oz). The other 330 ml (about 11 fl oz) stayed in the bottles.
We write when there is something to try. Nothing before that.
Rememilk is a bottle milk log in development, written by a parent. It is meant to record what was offered, what was left and what the baby drank. It is being built around bottles that are not one number, such as a mixed bottle of breast milk and formula. It is not released yet. The printed page works today.
Bottle feeding log Date 17 Oct 2026
| Offered | Left | Drank |
|---|---|---|
| 910 ml about 31 fl oz | 330 ml about 11 fl oz | 580 ml about 19.6 fl oz |
The same page, 18 days
From 1 to 18 October 2026 we wrote down what we offered and what was left. Averaged over those 18 days:
| Per day, all bottles | |
|---|---|
| Offered | 865 mlabout 29 fl oz |
| Left | 259 mlabout 8.8 fl oz |
| Drank | 606 mlabout 20.5 fl oz |
The left column was 29.9% of what we offered. A log with only the first number would have read 865.
This is one family’s log, not a survey of families.

Bottles that are not one number
These are the cases a plain “one feed, one number” log gets wrong. Rememilk is being built around them.
-
A mixed bottle.
Example: breast milk 2 fl oz (about 60 ml) + formula 1 fl oz (about 30 ml) = 3 fl oz (about 90 ml) offered. Both lines sit in one bottle, so the feed counts once.
-
A feed at the breast.
It has no ml. The day reads “300 ml measured + 2 nursing sessions not measured”, never a false 0.
-
Numbers as you write them.
Type 3.5 fl oz and it stays 3.5 fl oz (about 104 ml). Nothing is rounded to a neighbor.
Planned features. Not available yet.

Whose numbers are these?
Ours, from one family’s log. We share no names, birth dates or photos.
