If you eat chili peppers in moderation while breastfeeding, it will not have a corresponding effect on the baby, because after all, you do not eat chili peppers every meal every day. You should pay proper attention to the diet during breastfeeding, such as not eating foods that return milk, and not eating foods that are relatively cold, because eating cold foods can cause diarrhea in babies. In addition, do not eat foods that return milk, as they will cause a significant decrease in milk production. Also, during the breastfeeding period, you should strengthen nutrition, eat more food with protein, and eat fresh fruits and vegetables in moderation, which will help to improve the quality of breast milk.
