Formula-fed babies usually have stools that are earthy or dark yellow or gold in color. Formula-fed babies usually have stools that are earthy yellow, dark yellow or golden yellow, and the color of the stools may vary depending on the type of formula. The bowel movements are also less frequent than those of breastfed babies, thicker in texture and slightly more smelly. This is due to the high protein content in the formula, which produces a heavier odor when it breaks down. If your baby has hard lumps or fewer bowel movements after formula feeding, you need to consider whether your baby is suffering from indigestion as a result of formula feeding, and also pay attention to adjusting the amount of feeding. Note that formula-fed babies are prone to dry stools, constipation and other adverse conditions, usually pay attention to the appropriate increase in water intake. If the baby after eating milk powder appeared uncomfortable symptoms, should promptly seek medical treatment, so as to avoid serious consequences.
