A quick query - I am currently mixed feeding and expressing every 4 hours which gives me enough to alternate formula with breastmilk. My question is whether it is the number of times I express in 24 hours that is important to keep up supply, or is it having the expressing sessions spaced evenly apart which is more important? I.e. could I do six sessions across the day/eve and drop one of the middle-of-the-night ones, rather getting up specifically to express because it's 4 hours since the last session, in addition to getting up to do feeds?
