Short Answer: Yup. Green, brown, light yellow, and a seedy mustard color are all normal.
The variations in the color of your baby’s bowel movement depends on whether they are drinking formula or breast milk. If it’s breast milk, the color may be different depending on whether it’s fore-milk (milk at the beginning of a feeding) or hind milk (from the end of a feeding).
You can pretty much ignore the color of your baby’s poop unless it’s white and chalky, thick and black, or red. If this is the case, contact your doctor as those colors may indicate an illness.
Also, don’t stress out too much about how many bowel movements your baby has a day. Instead focus on how many wet diapers you change (there should be at least six a day). This indicates your baby is getting the nutrients and hydration they need.
