If I can only pump 3oz in a day, should I give it to him oz at a time, all at once in morning, or evening? or does it matter?

A dr once told me to take my vitamins in the evening. Something about the flora in our gut is more active in the evening and absorbs more then than if you'd take them in the morning. So now I'm pumping and only producing 3oz in one day. Sometimes I would give an ounce every 6 hours, sometimes save it during the day and give all at once. But now I'm wondering is it better for me to give it to him at a certain time of day? Does anyone have any input on this? At what point should I stop pumping bc the amount I'm producing is so small is it worth it?
