Hi,
I had some of the same issues however when my son was born right from the start the first day they told me one of the heel prick blood tests was positive and he could not take my milk so I started pumping in the Hospital then another test was done and after a week I could breast-fed. It was hard at first he was now a week old and my supply was low but I just fed him more often and drank lots of water to build up my milk. Then at 4mos. I had to take med and he went on formula for a week I pumped and tossed and we where back to BF. Long story short He was breast-fed until 14mos. He is now a happy 12yr old young man. Hang in there drink lots and lots to keep up supply when you are back breast-feeding.
