How do I keep track of mixed feeding?
Keep the parts of a mixed feed together while preserving the difference between nursing time, bottle volume and pumping.
The short answer
Record each part of the feed in the way it happened: nursing time and side, then any bottle or top-up with its milk type and measured amount. Log pumping as its own event. This gives you and your care team a clearer record than combining everything into one number.
Keep one feeding session, with separate parts
A mixed feed may include time at the breast followed by expressed milk or formula. Note when the session happened, how long your baby fed on each side if that detail matters to you, and any bottle or top-up that followed.
For a bottle, record the milk type and amount offered or consumed if you know both. If your clinician has asked you to track a particular amount, use their instructions for which number to record.
Keep pumping in its own record
Pumping records what you expressed; it does not tell you what your baby drank. Keeping it separate avoids adding expressed milk to a feed before the baby has taken it. Later, if the milk is used for a bottle, record that bottle as part of the baby's feed too.
Don't turn nursing minutes into millilitres
Time at the breast can help you remember how long a feed lasted, but it is not a measurement of milk transfer. If you are worried about intake, ask a qualified professional to assess your baby and the feed. Use an individual plan if one was provided.
Keep the log useful, not burdensome
Choose only the details you need to remember or share. BabyDays can keep breast time, bottle amounts, top-ups and pumping in one timeline while leaving those measurements distinct. The log is there to make a handoff easier, not to judge how a feed went. For general timing context, see how often you may need to feed a newborn.
