Advice needed from fellow expressers. My baby is 8 days old and is fed almost exclusively expressed breast milk. His consumption seems to be going up exponentially so my question is - how much is too much? He's confidently polishing off 100ml in a feed today, every 3-4hrs. At his last feed he had 100ml, seemed satisfied and then started furiously rooting less than an hour later. He seems to be really chunking up and I don't want to over feed him. Not due to see midwife again until Saturday. Thanks in advance.
