And all I can say is that a baby who has just had 4 ounces to eat is not starving or even hungry. Babies are compelled by instinct to seek to nurse pretty much constantly. There are theories as to why this is, and basically they boil down to the fact that for most of human history when we were nomadic hunter gatherers with little shelter and certainly nowhere an infant could be put down safely, a baby who was held and nursed most of the time lived, and babies who were put down and did not object did not. If you think about infant primates and their moms, they are never put down.
So baby acting
like they are starving (by which I assume you mean, crying to nurse (?) after nursing for some time or after a bottle or even if they have fallen asleep and you try to put baby down, that crying to nurse again is normal and not necessarily related to actually needing or wanting anything else to eat.
