My formula-fed baby's stool is darker and smellier than when I was breastfeeding. Why?

The real reply from the in-app AI advisor

Darker, more noticeably smelly stool in formula-fed babies is completely normal. The reason: formula has higher iron content than breast milk, and baby's digestive system processes formula protein differently. The color is usually darker (greenish-brown) and consistency is firmer, more like paste. If your baby's stool isn't very hard, very dry, or bleeding, and he's pooping easily—this is a sign of healthy digestion. Only worry if stool becomes hard/dry/with blood, or your baby shows distress, vomiting, or other discomfort—then talk to your pediatrician.
