My baby kits were fine yesterday morning. (They were 5 days old.) I lost 2 that night. It seemed to be some kind of illness. They would open their mouths and sort of scream and struggle to breathe. They seemed to have been fed because their bellies were rounded. Then this morning I checked and had lost two more. Two others seemed barely alive. I seemed to keep them alive by massaging their chests slowly. I now have only two surviving, one barely. What can I do to save them? What are they dying from? I noticed they were wet yesterday afternoon; like the mother had peed on them, so I warmed them up in a towel. Did I do more harm than good?
