The baby’s body functions are running at high speed during the day, and at night the body hormones will drop significantly, and certain diseases are likely to occur, which is one of the reasons why babies are prone to fever at night. Fever is mainly a reaction to the stimulation of the body by pathogens, such as bacteria and viruses that produce an immune response to the body, and the immune process can easily lead to immune disorders, so many children are prone to fever. Some parents like to give their children high-calorie food before bedtime, such as milk, nutrition, etc. After going to sleep, the stomach and intestines can not be better digested, and will produce a lot of heat, easily induced fever. So it’s best for your baby not to drink milk at night and not to eat high-protein, indigestible food to avoid inducing fever.
