My granddaughter Khloe is 5 weeks old and has CF. She was taken 4 weeks early because of a blockage in her intestines. She is recovering from that procedure, but she can't gain weight. They can't do the surgery to put her back together until she gains some weight. She weighed 4 lbs. 15 oz. at birth. She lost down to 4 lbs. even and then gained to 4 lbs. 13 oz. That was when she was on the TPN. They have removed all the added liquids and are just using formula. She takes the enzymes, but nothing is working. She is back down to 4 lbs. 9 oz. Also she may be having liver problems. She is very yellow. Anyone been through this situation or any advice?
