The amount of quantity: The amount of quantity mentioned here refers to the amount of liquid that the child excretes out of the body via urine within 24 hours, and should also be counted if the child’s stool is very thin. If the child is small, you can use a diaper, buy a small bench scale, weigh the diaper before using it, and then weigh it after the child has urinated or defecated, and the difference between the two numbers is how many grams, which means how many milliliters of urine or variables the child has that time. The child’s intake: The intake here is the amount of fluid the child takes in during 24 hours, and should be distributed to be given evenly over 24 hours, preferably with multiple meals slightly. This includes foods containing liquids such as milk, rice flour, porridge, fruit juice and potions; dry foods such as steamed buns and rice are not included. The amount of food to be given to the child varies depending on the child’s weight, severity of the disease, etc. Follow the doctor’s instructions at the time of discharge and limit the child’s intake according to the child’s condition after discharge. If the child sweats a lot, you can increase the amount of intake for the child. Generally speaking, if your child has no other problems and has swollen eyelids and a full fontanelle, it means that your child’s intake may be too much. In principle, a child’s daily intake should be equal to or slightly more than his or her output; however, since water can be lost through the skin and breathing, the intake may be greater than the output in reality, but the difference between the two should not be too large. If the intake is much greater than the output, and if the child has eyelid edema, the child may have a low output and can take diuretics appropriately.
