How much expressed milk per day/stage?

First week they don't need more then 30mls going a max of 3 hours. By week 2 they may be ready to go up to 60ml (mine didnt get there till a month old she would have on average 40ml). And you steadily increase until you get to 4oz. Most babies don't need to take more then 4 to 4.5oz. Breast milk digests quicker so they'll always need feeding more regularly

Thank you! That’s good to know as that’s what we’ve been doing so that’s good. Though our baby has lost quite a bit of weight.

@Sophie except fornula fed babies breast fed babies do loose weight. As long as it's 7% or under they won't worry.
