Ok so typical intake for that period of time would be about 10-15 ounces. But not all babies take in the typical amount! My best suggestion is to try to increase what baby will eat during the day but try not to get too hung up on the numbers, if that makes sense.
6-8 hours is a long sleep stretch ("Sleeping through the night" is actually defined as 5 consecutive hours) and many babies do not start sleeping that long consistently until they are well over a year old. Again when a baby does sleep that long early on, whether they do so on their own or due to some other reason, they often change that sleep pattern a few months later. More food into baby during the day may help baby sleep a bit longer at night, but you also may be many months away from baby consistently sleeping long stretches again.
Actually the most common issue is something called "excess lipase" and it can make expressed milk smell and taste a bit soapy, some people say the smell is "metallic." The milk is not bad, it is perfectly safe to drink, and many babies will drink it fine. But some babies react to the smell and will not.
This issue appears after expressed milk has been stored, usually when it has been frozen, but in some cases even after refrigeration. If baby is reacting the same way to "fresh" milk and there is no soapy smell, you can probably rule out lipase. Yes actually spoiled milk would smell spoiled.
It is quite simple and common sense, really. I will link a video....
