#AskTheExpert whenever my kids go for loo it smells very bad kindly help should I need to check with doctor.

A. As their gut becomes colonized with bacteria, the stool becomes smellier. 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.
