It is best not to give your child egg custard when your baby has a fever. It is generally best not to give your child egg-based or seafood-based foods when he or she is sick and has a fever, as this will make the fever less likely to get better and will aggravate the child’s discomfort. It is best not to eat egg custard when your baby has a fever because it is not very easy to digest. You need to eat light, easy-to-digest food, drink plenty of water, and aim for a diet that is light, easy to digest, and rich in vitamins. You should eat liquid or semi-liquid food, such as rice soup, thin rice or noodles. In clinical practice, especially for babies with digestive tract infections accompanied by fever, it is generally not recommended to give high-protein foods such as eggs, which can reduce the burden on the baby’s digestive tract to help maintain the child’s digestive function.
