Wren seemed to lose weight again today although I have to wait for the morning weigh-in to confirm. Before the 6pm feed his BEFORE weight had dropped 170g from the last time I fed him at noon. I spoke to the nurse and suggested his supplemental feed (of 65g) was not enough. When I nursed him at 6pm he drank 122g of milk - a new record.
She called the doctor and received approval for an increase to 100g per feed. I hope that helps him out a bit.
