Hello Tresa,


Early feces in newborns are black in color and shaped like a thick, sticky liquid called meconium. The baby will defecate meconium in the first 24 hours for up to 5-6 days, then it will turn into normal stools that are yellow or greenish (breast milk) or brownish like peanut butter (formula milk). Infants <6 weeks who are breastfed can defecate 3-12 times per day.


Black particles and fibers such as threads in baby's stool can be caused due to food content that is not digested properly. Some foods that can cause complaints such feces are bananas, blueberries, cherries, foods that can change the color of the stool to be darker, strawberries, plums, foods high in iron and others. Sometimes baby stools that are given breast milk can have the consistency of seeds and are still normal. Baby feces are greatly influenced by the quality of breast milk and the types of food consumed by the mother during breastfeeding.


The thing to watch out for is if there is a drastic change in the consistency of a baby's stool, the baby's stool is accompanied by blood / black such as meconium / pale-white, the baby is fussy or restless when defecating, the baby's stomach is enlarged and the baby is not defecating at all. If you find something like that, you should bring your child to see a doctor. Thus the explanation from me, hopefully useful.
