how many oz of milk should my 2wk old be drinking during feeds?

hello!! my baby is 2wks and normally eats 1-2oz. of milk per feed. she does well with holding it down and there’s moments where she doesn’t. she also gives a good amount of hunger cues after feeds even with 2oz. should she be having more by this point, in terms of milestones? i worry i’ll over feed and we all know spit up can be feel really scary so i try to avoid it but wouldn’t want to under feed either. i do track her diaper changes and feeds and everything check outs, but any recommendations of oz. she should be having? thank you!
