Hang in there. I can only imagine how frustrating this must be for you. Seems that the issues are pretty clearly medical and not just breastfeeding troubles. I would be VERY assertive about your breastfeeding desires and push to make it happen. I hope that your hospital will make things comfortable for you. I think our babies are about the same age. We were readmitted at 10 days for an infection. Overall, it was a good experience. Our hospital has double rooms on the pediatric floor: one bed for patient and one real bed for a parent in addition to the fold-out chair thing. They provided a parent tray at each meal and let me use a hospital pump (I wanted a bit of a stash to leave if I needed to get out of the hospital for my sanity).
When you're admitted you will be in pediatrics rather than post-partum. I found that the pediatric nurses were all over the map as far as breastfeeding knowledge and supportiveness. I quickly realized that I would have to take their advice on medical stuff (IVs, vital signs, labs) and leave it on feeding and parenting (how much I held the boy, how I fed, etc.). Our hospital had great IBCLCs on staff. I requested to see the LC when we were trying to rebuild supply after he lost interest due to the infection. When the other nurses tried to say other things about breastfeeding, I just politely told them I was working with the LC and following her advice. With new nurses almost every shift I think I would have gone batty if I tried to accommodate the theories of 20 each one.
Hang in there. Keep loving your baby and working with your medical team.
