If you use too much water, the drink will be less effective. Stir well, and give to the child to drink in a cup or feed with a spoon. A child with diarrhoea needs food. It is often said that a child with diarrhoea should not be given any food or drink while the diarrhoea lasts. This advice is wrong.
Food can help to stop the diarrhoea.
Also, diarrhoea can lead to serious malnutrition unless parents make a special effort to keep feeding the child during and after the illness. A child with diarrhoea usually has less appetite, so feeding may be difficult at first. After the age of about six months, all children need extra food in addition to breastmilk. Add one or two teaspoonfuls of oil to cereal and vegetable mixes if possible. Also good for the child are yoghurt and fruits.
