Laurie,
If a baby isn't getting enough milk at breast and there isn't enough
human milk available, I would supplement with ABM. The baby needs
protein and other nutrients, not just sugar. I believe this is in
agreement with most recent literature.
D5W doesn't have enough sugar to do much good if you are worried about
hypoglycemia. D10W is too likely to cause a rebound hypoglycemia. The
neonatologists in our area are recommending 24 calorie formula for
hypoglycemia.
