There is no scientific evidence that dairy must be avoided after a C-section unless you have a specific lactose sensitivity or your baby shows signs of Cow Milk Protein Allergy (CMPA), which is distinct from lactose intolerance. Dairy provides essential calcium and protein helpful for postpartum recovery. While moderation is key—especially with caffeine to avoid excessive intake—you can generally return to your normal diet, focusing on nutritious, easily digestible meals and minimizing overly oily or spicy foods if they cause digestive discomfort.
