My baby is 2 weeks old and will not latch on to my breast, so I have been pumping only. I pump after each feeding. I pump both breast at a time and they currently each produce about 2 ounces at each session. I am currently feeding him 2 ounces each feeding. Does this sound right? Is there anything more I should be doing? I also think he is going through a growth spurt as he is eating every hour and a half.
