If a child refuses to eat milk after the fever has subsided, it is mainly due to the following reasons: 1. Temporary refusal to eat milk after a child has a respiratory infection or an infectious disease, because children with acute tonsillitis or measles, rubella and other diseases have a fever, which often causes a temporary decrease in digestive function, and children will refuse to eat milk after the fever has subsided. 2. Due to the sequelae of digestive tract infection in children, if children with acute enteritis have fever and diarrhea, although the fever has subsided, the children’s enteritis symptoms have not completely improved, and they may refuse to eat milk at this time.
