Probably like many of you, we have been putting a few scoops of preemie formula in a bottle of breastmilk every day in addition to our regular breastfeeding so LO can get some extra calories. This has iron, and we also add iron via dropper. Although in her early days, she'd have a poopy diaper every 5 minutes, at 4 months, she takes about 4 days to go and has a lot of straining. Her doctor says this is fine but to watch for blood. The last few diapers look like typical bf diapers but there are some thicker black globs. They almost look like cat fur, but they're not. I read this could be caused by iron, but how can I tell if this is iron or blood? Thanks!
