How much milk is ‘normal’ to express?
Between 1-6 months, a breast/chest fed baby drinks an average of 750ml (25 oz) per day, and this amount doesn’t increase as they get older!. If you’re expressing exclusively and aiming to build a full supply, this is a rough amount to aim for.
However, if you’re exclusively breast/chest feeding and trying to pump as well, sources state that ‘normal’ output could be ½-2 oz (both breasts) per session - thats anywhere between 15-60ml. - So it is ‘normal’ for most people to need a few pump sessions to make up ‘a feed’ (and of course feed sizes vary too!). When parents see pictures of enormous pumped bottles like this, it can understandably put the fear in them.
At the end of the day, ‘normal’ pumping depends on a variety of factors including our aims, our bodies, our babies and our journeys up until the point at which we start. It can be really helpful to talk these things through with someone qualified, and also to consider:
🍉How much we’re aiming to pump, and why
🥝What kind of pump we are using - old/new, wearable, double, single - the list goes on…
🍒Is our fl**ge correctly fitted
🥑Are we maximising our oxytocin before and during pumping - this controls our ‘letdown’ of milk
Fruit for thought! 🍉🍇🍒.
