Consumption of milk

Hi mummies, may I know how much milk should be given for a 6 days old infant? And the feeding interval? My confinement nanny seemed to be overfeeding my LO, but she said it is okay as some babies tend to drink more? As long as he cries, CN will deem fit my LO is hungry after checking that it is not due to dirty diapers. I cried so badly despite I told her he shouldn't be drinking 50ml every 2hrs..
