When a baby has a cold, symptoms can include fever, coughing, a runny nose, and sneezing. Some may also experience vomiting, diarrhea, and loss of appetite. Thus, a cold can lead to a decrease in digestive function and loss of appetite. Regarding diet, it is important to provide light, easily digestible foods. If the baby is breastfed, the mother should also consume light and easily digestible foods; if the baby is formula-fed, the formula should be diluted. It's appropriate to add some supplementary foods such as vegetables and fruits. Meanwhile, spicy, stimulating, greasy, and hard-to-digest foods should be temporarily avoided during this period.
