When a baby has a cold and vomits, it is usually a gastrointestinal cold caused by a cold virus. At this time, the first thing to do is to give the child a 3-hour water and food fast, and after 3 hours, give the child medication to relieve vomiting, such as morpholine suspension. In addition, give the child antiviral medication, such as Four Seasons Antiviral Combination or pediatric black beetle fever granules. Give the child more water to promote the excretion of urine, which facilitates the excretion of viruses and toxins. Give your child simple, light and easily digestible food. At this time, you can eat rice soup such as rice porridge or millet porridge, or you can eat thin rice paste. Observe your child’s condition and if vomiting continues, take your child to the hospital quickly.
