my son is 6 months old and he is having smelly loose motions from two days

A. This is a normal process. Breast-fed babies usually don't have very smelly stools, while formula-fed babies often have a more pungent odor. Generally speaking, poop stinks, and there's not much we can do about it. In some cases, extremely foul-smelling stool may be an indication of inadequate absorption of nutrients.
