It is possible to drink glucose water when your baby has a fever. When a child has a fever, the body is in a state of greater catabolism than synthesis, and it is important to give the child energy and heat at this time, so glucose water is okay to drink. However, if your child is sweating a lot after taking fever-reducing medication, you should also add an appropriate amount of salt to the glucose water to prevent dehydration and to replenish the electrolytes and water lost by your child. However, glucose water is not suitable to be brewed too thick, as it will taste bad at this time and may easily trigger the occurrence of vomiting. In addition, the excess sugar tends to remain in the mouth, causing bacteria to multiply in the mouth, which may cause other types of infections and aggravate the child’s fever.
