question: My LO is 5 months old. He is exclusively breastfed. Today he had black specks in his stool. I gave him iron and vitamin D. But I give him those every other day (doc perscribed to do it every day-I didn t want to constipate him so I do every other). He has been extra fussy for the past 2 days but nothing major. He does not have a fever. Does anyone know what this could come from?
