How are you going with expressing so far hun? It can take a while to get the hang of it.

Babies drink the same amount of milk daily from 1 month to 6 months of age - that means that after the first 3 or 4 weeks, the amount of milk drunk doesn't change as they get older. It then will start to lessen a little bit when they start solids (but shouldn't drop by much until they are nearer to 1 year of age). The amount drunk by babies each day varies a lot from baby to baby - some drink about 500mls a day, and others 1000ml a day. Usually mums work on an average of 750ml per day, and divide that by the number of feeds in 24 hours to work out the approximate amount per feed. Like adults, babies don't have the same amount at each feed, but that it is a good guide to how much you will need. Also, many babies will drink less from a bottle and wait until mum is home to have an extra big bf, so don't worry too much if you have less EBM than you think you will need.

As a PP said, EBM will keep for about 6 hours at under 25 degrees. Not all babies need it warmed but some will. Here is the ABA guide to storage of EBM - Australian Breastfeeding Association -.

Best of luck hun.
